[0034] Figure 1 An application scenario diagram of the data transmission method, apparatus, device, medium, and program product according to an embodiment of the present disclosure is schematically shown.
[0035] like Figure 1As shown, the application scenario 100 according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, and a server 105.

[0040] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.
[0041] The following will be based on Figure 1 The scene described by Figure 2~Figure 8 The data transmission method of the disclosed embodiment is described in detail.
[0042] Figure 2 The flowchart of the data transmission method according to the embodiment of the present disclosure is schematically shown.
[0043] like Figure 2 As shown, the data transmission method of this embodiment includes operations S210 to S250.
[0044] In operation S210, the received first request is parsed, and a blueprint parameter pool is constructed based on the parsing result; wherein the parsing result includes at least functional information and requirement information, both of which are used to characterize the purpose of the blueprint parameter pool, and the requirement information is a refinement of the functional information.
[0045] In some embodiments, after receiving a first request sent by a user, a corresponding blueprint parameter pool is constructed by parsing the first request.
[0046] A blueprint is a predefined template or script that describes how to configure, deploy, and manage a set of resources or services. A blueprint may include a series of steps that define the entire process from creating a resource to configuring its properties. A blueprint parameter pool is a place to centrally store and manage parameters. These parameters are defined during blueprint design and referenced by different operations or components as needed during blueprint execution. Parameters in a blueprint parameter pool can include various types of data, such as strings, numbers, Boolean values, etc., which are used to configure various properties of cloud service resources.
[0047] During the specific implementation process, the first request is sent by the user through an application programming interface (API) call, a web interface operation or other communication methods. By parsing the received first request, the specific functions (function information) that the user wants to perform and the specific parameters or conditions (requirement information) required for these functions are identified.
[0048] In operation S220, in response to receiving the second request, a target parameter is selected from the blueprint parameter pool and an operation instance is generated based on the target parameter; wherein the operation instance is used to enable a designated node to execute a specific business logic.
[0049] In some embodiments, the second request may include the first information and the second information. The second information is used to characterize the requirements of the operation instance, and the first information is the information of the target parameters required to construct the operation instance. The operation instance is generated by parsing the target parameter information and the operation instance requirement information in the second request. One business logic may correspond to one operation instance, or may be split into multiple operations, corresponding to generating multiple operation instances, which are respectively executed by multiple identical or different nodes to complete the business logic.
[0050] During the specific implementation process, the second request may also include a blueprint identifier, which is used to quickly locate the corresponding blueprint parameter pool and generate an operation instance based on the target parameter information and the operation instance requirement information.
[0051] In operation S230, attribute information of a plurality of nodes is acquired.
[0052] In some embodiments, the attribute information includes at least one of the state information and configuration information of the node, the state information is used to represent the dynamic information of the node at the current moment, and the configuration information is used to represent the role information of the node.
[0053] Optionally, the state information of the node is used to represent the dynamic information of the node at the current moment, such as the current resource usage, health status, load status, etc. of the node.
[0054] The configuration information of a node is the static or configurable properties of the node, such as the role information and labels of the node. The role information includes, for example, the specific responsibilities and functions of the node in the cluster. Allocating operation instances based on the role information of the node can effectively optimize the rationality of resource allocation, improve the stability of the system, and support complex scenarios.
[0055] In the specific implementation process, the node role can include multiple aspects, depending on the type and purpose of the cluster. Taking the node roles of master node and slave node as an example, the master node is mainly responsible for processing write operations and some key read operations. It is the main storage and management node of data and has high performance requirements. The slave node is mainly used to undertake read operations and data backup tasks, and has lower performance requirements. The master node and the slave node differ in both functional responsibilities and performance requirements. Therefore, different implementation examples can be sent to corresponding nodes based on role information to improve resource utilization and stability.
[0056] In operation S240, a correspondence between each node and an operation instance is determined based on the role information configuration information and / or the state information.
[0057] In some embodiments, if the attribute information of a node is different, the operation instance corresponding to the node may be different. Determining the correspondence between a node and an operation instance based on the attribute information of the node can effectively improve the flexibility and accuracy of the operation instance distribution, achieve load balancing, optimize the execution efficiency of each operation instance, and improve the utilization rate of node resources.
[0058] In operation S250, based on the corresponding relationship, the control middleware sends corresponding operation instances to multiple nodes respectively; wherein nodes with different roles receive different operation instances.
[0059] In some embodiments, the correspondence may include, for example, a first correspondence and a second correspondence. In the first correspondence, nodes with the same role information correspond to the same operation instances, and nodes with different role information correspond to different operation instances. In the second correspondence, nodes with the same role information may also correspond to different operation instances.
[0060] In the disclosed embodiment, the middleware is used as an intermediate component for message transmission, and a middleware embodiment is shared on multiple nodes to achieve efficient resource utilization and simplified management. The middleware service is logically regarded as a single entity responsible for processing requests and responses from multiple nodes.
[0061] The distribution of operation instances based on middleware can effectively decouple the sender and receiver of messages, improve the flexibility and scalability of message delivery. And message delivery through middleware can effectively improve the response speed, effectively handle a large number of concurrent requests, and reduce the pressure on the server.
[0062] The data transmission method provided by the embodiment of the present disclosure can effectively improve the flexibility and response speed of the generation of operation instances by selecting target parameters from the blueprint parameter pool to generate operation instances, so as to quickly generate corresponding operation instances according to different business scenarios or requirements, and the design of the blueprint parameter pool can effectively realize the dynamic management and maintenance of the configuration parameter set, so that the configuration parameters can be flexibly adjusted according to business requirements, thereby improving the scalability of the configuration parameters. In addition, the embodiment of the present disclosure sends operation instances to each node based on the corresponding relationship by the middleware, which can effectively improve the overall efficiency and accuracy of node configuration and management. The operation instances directly act on the specified nodes, so that these nodes can quickly adapt to new business logic or configuration requirements, effectively improving the stability and reliability of node management.
[0063] Figure 3 The flowchart of constructing a blueprint parameter pool in response to a received first request according to an embodiment of the present disclosure is schematically shown.
[0064] like Figure 3As shown, in response to the received first request, building a blueprint parameter pool in this embodiment includes operations S310 to S320.
[0065] In operation S310 , a target blueprint framework is selected from a plurality of pre-built blueprint frameworks based on the functional information.
[0066] In some embodiments, the functional information is used to characterize the service or operation type involved in the first request, which defines the basic tasks or functions that the system needs to perform. For example, the first request may be a request to create a new database instance, run a data analysis task, or access a specific storage resource. Based on the parsed functional information, one or more blueprint frameworks that match the target functional items can be selected from the blueprint framework library. Among them, the blueprint framework library includes multiple constructed blueprint frameworks, which are standardized templates designed for different types of functions and services. Each blueprint framework contains a series of predefined components, configurations, and processes for rapid deployment and configuration of services.
[0067] In operation S320, a blueprint parameter pool corresponding to the target blueprint framework is constructed based on the demand information.
[0068] In some embodiments, the requirement information is a parameter or condition further refined on the basis of the function information, and the requirement information specifies the specific configuration, resource amount, performance requirements, etc. required to perform the task or function. Based on the requirement information obtained by parsing, a blueprint parameter pool corresponding to the target blueprint framework is constructed, wherein the blueprint parameter pool contains a collection of all necessary parameters and configuration information for guiding the implementation and deployment of the blueprint framework.
[0069] In the specific implementation process, the required target blueprint framework is first clarified through the function information, wherein the function information can be either the relevant information of the basic tasks or functions to be performed, or directly the blueprint identifier. In the case where the function information is the relevant information of the basic tasks or functions to be performed, the server automatically selects a suitable blueprint framework from the blueprint framework library as the target blueprint framework by analyzing the function information. In the case where the function information is a blueprint identifier, the corresponding blueprint framework is directly searched from the blueprint framework library based on the blueprint identifier as the target blueprint framework. After selecting the target framework, a blueprint parameter pool corresponding to the target blueprint framework is constructed according to the requirement information obtained by parsing, wherein the blueprint parameter pool contains all the parameters and configuration information required when executing the target function or task. Among them, the requirement information may include, for example, a parameter list, a parameter value (or a parameter selection condition), etc. And, if the parameter is a dynamically generated parameter, in addition to the parameter value, the requirement information should also include the necessary conditions for generating these values.
[0070] The disclosed embodiment determines the target blueprint framework based on the first request and constructs a blueprint parameter pool corresponding to the target blueprint framework, which can effectively improve development efficiency, avoid the tedious process of designing an architecture from scratch, and improve the scalability and maintainability of the blueprint parameter pool, so that the system can flexibly adapt to different business scenarios and changes in demand.
[0071] Figure 4 The flowchart schematically shows, in response to receiving a second request, selecting a target parameter from a blueprint parameter pool and generating an operation instance based on the target parameter according to an embodiment of the present disclosure.
[0072] like Figure 4 As shown, in response to receiving the second request, this embodiment selects target parameters from the blueprint parameter pool and generates an operation instance based on the target parameters, including operations S410 to S430.
[0073] In operation S410, the second request is parsed to obtain first information and second information; wherein the first information is used to determine the target parameter, and the second information is used to characterize the operation instance requirement.
[0074] In some embodiments, a parsing operation is performed on the received second request, and the second request may include multiple types of information, such as user input, system status, external data, etc. The first information and the second information are extracted from the parsed information.
[0075] In operation S420, a target parameter is selected from a blueprint parameter pool based on the first information.
[0076] In operation S430, an operation instance is generated based on the target parameter and the second information.
[0077] In some embodiments, the first information is used to determine parameter requirements, which may be necessary to perform a certain operation. The required target parameters are searched and determined in the blueprint parameter pool according to the first information, and these target parameters will be used for subsequent operation instance generation. Among them, the first information may include, for example, data types, ranges, default values, etc. After determining the target parameters, a specific operation instance is generated based on the target parameters and the second information, wherein the number of operation instances is not less than 1, and the operation instance contains all the information required to perform the current operation, such as operation type, parameter value, execution conditions, etc.
[0078] In the specific implementation process, each business logic may correspond to an operation instance, or may be split into multiple operations, and multiple operation instances may be generated accordingly. When the business logic corresponds to multiple operation instances, the second request may include multiple sub-requests, wherein each sub-request has corresponding first information and second information, and based on the first information and second information of each sub-request, the target parameter corresponding to the sub-request is determined and the operation instance corresponding to the sub-request is created. The generation process of the operation instance is dynamic and can be adjusted according to different requests and parameters.
[0079] In addition, the process of selecting the target parameter may also include: verifying the searched parameter. Specifically, it may be verified whether the searched parameter meets the requirements of the second request (such as the accuracy, applicability, and completeness of the parameter) and the constraints in the blueprint definition (such as data type, value range, etc.). If the searched parameter meets the user request requirements and the constraints, the searched parameter is determined as the target parameter.
[0080] The embodiments of the present disclosure dynamically generate operation instances according to different requests, which can effectively improve the flexibility and adaptability of the system and achieve efficient generation of operation instances.
[0081] Figure 5 A flowchart schematically shows an operation example based on target parameters and second information generation according to an embodiment of the present disclosure.
[0082] like Figure 5 As shown, the example of generating an operation based on the target parameter and the second information in this embodiment includes operations S510 to S520.
[0083] In operation S510, an initial instance is generated based on second information.
[0084] In some embodiments, the second information is parsed, initial instances are generated according to the parsed information, and necessary resources, such as network connections, database connections, etc., are allocated to each initial instance.
[0085] The second information is used to further describe or specify the specific requirements of the operation instance, which may include the specific type of operation, required resources, execution conditions, etc. The initial instance is generated according to the parsed second information, wherein the initial instance is a basic framework or template that can be created according to the general part of the second information or predefined rules. The initial instance contains the basic structure and attributes required for the operation instance, but has not yet filled in specific target parameters or execution details.
[0086] In operation S520, target parameters are assigned to corresponding initial instances to obtain operation instances.
[0087] In some embodiments, after the initial instance is generated, the acquired target parameters are assigned to the corresponding initial instance, and the target parameters in each initial instance are verified to ensure that the instance formed by the target parameters conforms to the expected format and range. After the verification is passed, the instance is determined as an operation instance. The target parameters are specific, customized information for each operation instance, and may include input data, execution parameters, configuration options, etc. By assigning corresponding target parameters to each initial instance, the initial instance is converted into a specific, executable operation instance.
[0088] The present disclosure generates an initial instance and flexibly assigns different target parameters to the initial instance without changing the basic structure or logic to obtain an operation instance, thereby improving the flexibility and scalability of the operation instance generation. As a predefined template or pattern, the initial instance can be repeatedly adapted in different contexts. By simply changing the target parameters, multiple operation instances with similar structures but different functions can be quickly generated, thereby improving the repeatability of the operation instance. In some special cases, the target parameters may need to be dynamically determined at runtime. By pre-generating the initial instance, the target parameters can be dynamically assigned at runtime according to actual needs, thereby realizing the dynamic operation instance construction process, effectively improving development efficiency, and enhancing the maintainability and scalability of the system.
[0089] Figure 6 The flowchart of obtaining attribute information of multiple nodes according to an embodiment of the present disclosure is schematically shown.
[0090] like Figure 6 As shown, the step of obtaining role information of multiple nodes in this embodiment includes operations S610 to S630.
[0091] In operation S610, the authentication credentials of each node are obtained.
[0092] In some embodiments, before calling the designated interface of the node, it is necessary to obtain the authentication credentials of each node, wherein the node credentials include the designated interface key, access token, etc.
[0093] Among them, obtaining the authentication credentials of the node includes centralized authentication and decentralized authentication. The corresponding authentication method can be selected according to the node architecture and permission settings. For example, if all nodes use the same authentication center or the authentication information is shared between the nodes, it means that each node corresponds to the same set of authentication credentials. Then, only one set of authentication credentials is needed to access the specified interface of all nodes. If the authentication mechanisms of each node are different and the authentication information is not shared between these mechanisms, the authentication credentials of each node need to be obtained separately.
[0094] In operation S620, a property acquisition request is sent to a designated interface of the node based on the authentication credentials.
[0095] In some embodiments, an attribute acquisition request is constructed based on the acquired authentication credentials, and the attribute acquisition request is sent to the designated interface of the node. The authentication credentials are included in the request header or request body of the attribute acquisition request, and are used to verify whether the attribute acquisition request is valid when the designated interface receives the request. If the authentication credentials of the attribute acquisition request are valid, the designated interface further processes the attribute acquisition request and generates response information based on the parsing result. The designated interface can be, for example, an application programming interface (API) interface, which can provide a standardized and efficient data acquisition method and ensure the consistency and accuracy of the data.
[0096] In operation S630, the received response information is parsed to obtain the attribute information of the node; wherein the response information is generated by the node based on the received attribute acquisition request.
[0097] In some embodiments, the response information received from the node is parsed to obtain the attribute information of the node.
[0098] The response information may include, for example, a status code, a response header, and a response body. The status code is used to indicate the processing result of the property acquisition request, and the response header contains metadata about the response, such as content type, cache control, etc. The response body contains the result data of the property acquisition request, for example, the status information and configuration information of the node, such as the role ID, role name, permission list information, resource status, etc. of the node.
[0099] The disclosed embodiment obtains the attribute information of the node based on the authentication credentials of the node, effectively improving the security of the node information and preventing unauthorized access and data leakage risks. The method can dynamically obtain the attribute information of the node, effectively improving the flexibility of obtaining the node attribute information, and can quickly respond to business changes and improve the flexibility of updating the node attribute information.
[0100] The data transmission method provided by the embodiment of the present disclosure further includes: determining the correspondence between each node and the operation instance based on the state information and / or configuration information.
[0101] Based on the configuration information, a first correspondence between each node and an operation instance is determined; wherein, in the first correspondence, nodes with the same role correspond to the same operation instance.
[0102] In some embodiments, taking the case where the role information of a node includes a master node and a slave node as an example, the number of master nodes is 1, and the number of slave nodes is N (N is a positive integer).
[0103] If the correspondence between the node and the operation instance is the first correspondence, the same operation instance is sent to the nodes with the same role information. For example, operation instance A is sent to the master node, and the same operation instance B is sent to N slave nodes. Each node receives at least one operation instance, and the same operation instance can be sent to nodes with different role information at the same time. However, among the multiple operation instances received by nodes with different role information, there is at least one different operation instance. For example, the operation instances received by the master node include operation instance A, operation instance C1, and operation instance C2, and the operation instances received by the slave nodes include operation instance B, operation instance C1, and operation instance C2.
[0104] Or, based on the configuration information and the state information, a second corresponding relationship between each node and the operation instance is determined; wherein, in the second corresponding relationship, nodes with the same role correspond to different operation instances.
[0105] If the correspondence between the node and the operation instance is the second relationship, different operation instances are sent to nodes with the same role information. It is necessary to further determine the matching relationship between multiple nodes with the same role and each operation instance based on the status information of each node and send the corresponding operation instance to each node according to the matching relationship.
[0106] Figure 7 A flowchart is schematically shown for determining a second corresponding relationship between each node and an embodiment based on configuration information and state information according to an embodiment of the present disclosure.
[0107] like Figure 7 As shown, in this embodiment, sending different operation instances to nodes with the same role includes operations S710 to S720.
[0108] In operation S710, a target instance group corresponding to each node is determined according to configuration information of each node, wherein nodes with different roles correspond to different target instance groups, and the target instance groups contain different operation instances.
[0109] In some embodiments, the target instance group corresponding to each role node is determined according to the configuration information of the node. For example, all nodes whose node role is role 1 have a corresponding relationship with instance group A, and all nodes whose node role is role 2 have a corresponding relationship with instance group B. Instance group A and instance group B both contain multiple different operation instances.
[0110] In operation S720, based on the state information of the node, the target operation instance corresponding to the node is matched in the target instance group to obtain a second corresponding relationship between the node and the operation instance.
[0111] In some embodiments, the node status information is used to characterize the current available resources of each node, and may include, for example, node processing capability, memory size, storage capacity, current load, etc.
[0112] Different operation instances have different resource requirements (such as CPU resources, memory, network bandwidth, etc.). You can determine which nodes are suitable for executing specific operation instances based on the node attribute information and the resource requirements of each operation instance. For example, you can determine which node the operation instance in the instance group corresponds to based on the resource requirements of the operation instance and the remaining resources of the node. In addition, you can also consider the impact of resource utilization, load balancing, and communication costs between nodes on the corresponding relationship.
[0113] In the specific implementation process, the second correspondence between the operation instance and the node can be dynamically adjusted according to the change of the current resource situation of the node. For example, when the node load is too high, the middleware can migrate some operation instances to other nodes with lower load.
[0114] Exemplarily, nodes may include computing-intensive nodes (equipped with high-performance CPUs and large amounts of memory), storage-intensive nodes (equipped with large-capacity hard disks and sufficient I / O bandwidth), and general-purpose nodes (resource balance, suitable for performing multiple tasks). The types of operation instances may include big data analysis instances, machine learning training instances, file storage service instances, etc. Among them, big data analysis instances need to process a large amount of data, with high requirements for CPU and memory, but always have requirements for storage and I / O bandwidth; machine learning training instances are usually computing-intensive tasks, with high requirements for CPU resources, GPU resources, and memory; file storage service instances need to continuously read and write a large amount of data, with high requirements for storage and I / O bandwidth, but relatively low requirements for CPU and memory. By analyzing the requirements of the operation instance and the node resources, a corresponding relationship between each node and the operation instance is established to send each operation instance to the most suitable node. For example, a big data analysis instance can be deployed on a computing-intensive node to shorten the data analysis time; a file storage service instance can be deployed on a storage-intensive node to ensure rapid response and stability of data access, etc., thereby achieving optimal resource allocation and efficient utilization, which helps to improve the efficiency of business logic processing.
[0115] The data transmission method provided by the embodiment of the present disclosure sends operation instances based on the attribute information of the nodes, and can dynamically match the operation instances with the most suitable nodes according to the changes in the node environment, thereby improving the flexibility and reliability of the operation instance distribution and improving resource utilization and stability.
[0116] Figure 8The flowchart schematically shows a flow chart of controlling the middleware to send corresponding operation instances to multiple nodes respectively based on the corresponding relationship according to an embodiment of the present disclosure.
[0117] like Figure 8 As shown, based on the corresponding relationship, the control middleware of this embodiment sends corresponding operation instances to multiple nodes respectively, including operation S810 to operation S830.
[0118] In operation S810, a corresponding message format is determined based on configuration information of each node; wherein the message format includes a message header and a message body.
[0119] In some embodiments, the message formats corresponding to different nodes may be different. Therefore, it is necessary to first determine the message format corresponding to each node based on the node configuration information.
[0120] In the specific implementation process, the message format includes a message header and a message body, wherein the message header may include, for example, a target node address, a message type, an email, etc., and the message body may include the specific content of the operation instance.
[0121] In operation S820, a serialization operation is performed on the operation instance, and the operation instance after the serialization operation is encapsulated in a message body to obtain a message to be transmitted.
[0122] In some embodiments, after the message format is determined, a serialization operation is performed on the operation instance, and the operation instance is encapsulated in the message body, wherein the operation instance contains all necessary information required to perform the operation, such as the operation type, parameters, execution conditions, etc., and the information is converted into a format suitable for transmission through the serialization operation, and the converted information is embedded in the message body to obtain the message to be transmitted. The serialization operation can be implemented based on a preset serialization framework, and the serialization framework is used to convert the operation instance into a transmittable format, wherein common serialization frameworks include JSON, XML, etc.
[0123] Converting the operation instance into a message to be transmitted and sending it can effectively reduce the coupling between the sender and the receiver. If the operation instance is sent directly, the sender and the receiver must share the same operation instance type. Converting the operation instance into a message format and sending it can effectively reduce the dependency between the sender and the receiver, making it easier to expand and maintain. Converting the operation instance into a message format and sending it can achieve cross-platform interoperability. As a standardized format, the message format can be transmitted and processed across different platforms and languages, while the operation instance may be limited to a specific programming language or framework.
[0124] In operation S830, the message to be transmitted is sent to the middleware, and the middleware sends the message to be transmitted to the target node based on the corresponding relationship.
[0125] In some embodiments, after the message to be transmitted is generated, the message to be transmitted is sent to the middleware, and the middleware sends the message to be transmitted to the target node based on the corresponding relationship. During the transmission process, since different nodes may use different message formats, in order to ensure that the message can be correctly parsed and processed by the target node, the middleware may need to perform a series of processing on the received message to be transmitted, such as message format conversion, security encryption, load balancing, etc.
[0126] Middleware is a software component that can connect multiple systems and nodes, and is used to enable systems and / or nodes to work together. Middleware can provide a reliable data transmission mechanism between multiple nodes and / or systems to ensure that data is transmitted safely and completely between applications. In addition, middleware can also realize the conversion of communication protocols, so that different systems and / or applications can communicate seamlessly. Sending messages to be transmitted to the target node based on middleware can effectively improve the security and reliability of message transmission.
[0127] The data transmission method provided by the embodiment of the present disclosure dynamically adjusts the structure and content of the message based on the role information of the node, so that the system can flexibly adapt to different business scenarios and changes in demand, and uses the middleware as the transmission channel of the message, which can optimize the routing and distribution strategies of the message, ensure that the message can reach the target node quickly and accurately, and send and receive messages based on the middleware, without establishing a connection between the message sender and the receiver, thereby reducing the coupling between the sender and the receiver and improving the stability and reliability of message transmission.
