[0054] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0055] The asynchronous communication method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the target service node 102 communicates with each service node 104 in the asynchronous communication cluster through the network. The processing performance parameters of each service node 104 are obtained, and the first-level cluster and the second-level cluster of the asynchronous communication cluster are constructed according to the processing performance parameters of each service node.

[0056] In one embodiment, Figure 2 As shown, an asynchronous communication method is provided, which is applied to Figure 1 The target service node in is used as an example to illustrate, including:

[0057] S201, the target node in the asynchronous communication cluster builds a primary cluster and a secondary cluster in the asynchronous communication cluster according to the processing performance parameters of each service node in the asynchronous communication cluster; the primary cluster includes a primary master node and a primary slave node, and the secondary cluster includes a secondary master node and a secondary slave node.

[0058] In an embodiment of the present application, each service node generates a voting request based on its own processing performance parameters, and sends the voting request to the target service node. Optionally, each service node can read the processing performance parameters from a preset database; or, each service node can parse historical processing information to determine its own processing performance parameters. Further, the target service node parses each voting request to obtain the processing performance parameters of each service node, thereby constructing a primary cluster and a secondary cluster in the asynchronous communication cluster based on the processing performance parameters of each service node. Optionally, the asynchronous communication cluster includes multiple levels of clusters. In an embodiment of the present application, the asynchronous communication cluster includes at least a primary cluster and a secondary cluster. According to the processing requirements for the asynchronous communication cluster, the number of service nodes in the asynchronous communication cluster, etc., the asynchronous communication cluster can include a third-level cluster, a fourth-level cluster, etc.

[0059] Optionally, the target node can evaluate each service node according to the processing performance parameters of each server node to obtain an evaluation value of each service node, and can determine the service node with the highest evaluation value as a first-level master node, and determine the service node with an evaluation value within a preset range as a second-level master node, that is, a first-level slave node, and determine the service nodes other than the first-level master node and the second-level master node as second-level slave nodes.

[0060] Optionally, when a preset election requirement is met, a voting request sent by each service node in the asynchronous communication cluster is received, wherein the preset election condition may include: (1) the slave service node fails to receive a signal from the master service node within a preset timeout period; (2) ,in , Respectively represent the message waiting weights of the current service node and the main service node, is a constant, representing the node switching overhead coefficient.

[0061] S202, the target node receives a service request sent by other service nodes in the asynchronous communication cluster, and sends a reply message corresponding to the service request to the other service nodes according to the service request.

[0062] In an embodiment of the present application, after the target node receives a service request sent by other service nodes in the asynchronous communication cluster, it processes the service request. After completing the processing of the service request, it generates a reply message for the service request, and determines the initiating node that initiated the service request and the position of the initiating node in the asynchronous communication cluster based on the service request, thereby sending the reply message corresponding to the service request to the initiating node.

[0063] In the above asynchronous communication method, the target node in the asynchronous communication cluster builds a first-level cluster and a second-level cluster in the asynchronous communication cluster according to the processing performance parameters of each service node in the asynchronous communication cluster; the first-level cluster includes a first-level master node and a first-level slave node, and the second-level cluster includes a second-level master node and a second-level slave node; the target node receives the service request sent by other service nodes in the asynchronous communication cluster, and sends the reply message corresponding to the service request to other service nodes according to the service request. Through the cluster hierarchical service structure, the response message is distributed at multiple levels, and the dependence on the unified intermediate agent is removed. While improving the efficiency of message routing, the reliability of the system is greatly improved. After other service nodes initiate service requests, there is no need to repeatedly poll to obtain reply requests, which improves the efficiency of asynchronous communication.

[0064] In one embodiment, an implementation of the above S202 is provided, such as Figure 3 As shown, the above “sending a reply message corresponding to the service request to other service nodes according to the service request” includes:

[0065] S301, determining a message delivery path according to an identifier in a service request.

[0066] In an embodiment of the present application, the message delivery path can be directly determined based on the identifier in the service request; or, the path nodes in the delivery path can be determined based on the identifier in the service request, thereby determining the message delivery path based on the path nodes.

[0067] S302: Deliver a reply message corresponding to the service request to other service nodes according to the message delivery path.

[0068] In an embodiment of the present application, according to the message transmission path, the reply message corresponding to the service request is sent to the secondary master node corresponding to the target node, the secondary master node sends the reply message to the primary master node, and the master node transmits the reply message to other service nodes according to the message transmission path.

[0069] In the above application embodiment, the message transmission path is determined according to the service request, and then the reply message corresponding to the service request is transmitted to other service nodes according to the message transmission path, thereby improving the accuracy of message transmission.

[0070] In one embodiment, an implementation of the above S301 is provided, such as Figure 4 As shown, the above “determining the message delivery path according to the identifier in the service request” includes:

[0071] S401: If the other service node is a first-level slave node, determine the first identifier of the first-level cluster where the other service node is located and the second identifier of the other service node according to the identifier in the service request.

[0072] In an embodiment of the present application, if the other service node is a first-level slave node, since the second-level master node corresponding to the target node is a first-level master node or a first-level slave node of the first-level cluster, it is sufficient to determine the path from the second-level master node corresponding to the target node to the other service node, read the field of the target position in the identifier in the service request, and determine the first identifier of the other service node and the second identifier of the other service node.

[0073] S402: If the other service node is a secondary slave node, determine the third identifier of the primary cluster and the fourth identifier of the secondary cluster where the other service node is located, as well as the fifth identifier of the other service node according to the identifier in the service request.

[0074] In an embodiment of the present application, if the other service node is a secondary slave node, the path from the secondary master node corresponding to the target node to the secondary master node of the other service node, and the path from the secondary master node of the other service node to the other service node are determined, and the field of the target position in the identifier in the service request is read to determine the third identifier of the primary cluster where the other service node is located and the fourth identifier of the secondary cluster where it is located, as well as the fifth identifier of the other service node.

[0075] Optionally, a schematic diagram of the first cluster and the second cluster is as follows Figure 4AAs shown in the figure, the first-level master service node is responsible for consuming the response message queue and routing the message to the first-level slave service node; the second-level master service node is the same as the first-level slave service node, responsible for receiving and forwarding messages from the first-level master service node. The first-level slave service node and the second-level slave service node are both execution nodes. After receiving the request, the execution node starts asynchronous processing and synchronously returns the request success message. After the asynchronous task processing is completed, the execution result combined with the request unique identifier is pushed to the public response message queue. After the first-level master service node consumes the message, it first determines whether it is the current second-level cluster message. If so, it is forwarded within the second-level cluster, otherwise it is forwarded to the corresponding second-level cluster according to the request identifier.

[0076] In the embodiment of the present application, the asynchronous communication process of the asynchronous communication cluster may include:

[0077] (1) When the asynchronous communication cluster is started, the three service nodes of the same service name are regarded as a secondary cluster. First, an internal election is initiated to confirm the master service node. The master service node is initially set as the slave service node of the primary cluster by default. The primary cluster initiates an election to confirm the master service node of the primary cluster. In particular, during the first election period, if only one service node is started in the cluster, the service node automatically becomes the master service node until it receives a voting request from a service node with a higher election value;

[0078] (2) After completing the initialization of the network, the main service node starts to consume and forward the response message;

[0079] (3) After the networking is completed, service node 1 of microservice A becomes a slave service node and initiates an HTTP request in the business operation. The request generates a unique identifier for this request based on service identifier A and service node identifier 1 and is sent to the recipient in the form of a request header.

[0080] (4) After receiving the request, receiver B performs preprocessing operations and starts asynchronous task execution based on the request identifier, and then returns a successful request to inform the requester of asynchronous waiting. After receiving the response, service node 1 registers the current request to the listening queue and waits for the main service node to push the message result.

[0081] (5) After the asynchronous task is completed, microservice B combines the execution result with the request unique identifier and sends it to the asynchronous task response message queue, thus ending the request processing.

[0082] (6) After the primary cluster master service node consumes the response message, it pushes the message to the primary cluster slave service node A according to service identifier A. The primary cluster slave service node A is also the primary service node of the secondary cluster. At this time, the message is pushed to service node 1 according to node identifier 1.

[0083] (7) After receiving the response message, service node 1 ends the waiting state of the current request and removes the request identifier from the listening queue, completing the entire life cycle of this asynchronous request.

[0084] Optionally, within the secondary cluster, by identifying the status of the slave service node, the exception message can be processed. For example, if microservice B2, as a slave service node, is unexpectedly terminated during task execution, and microservice B1, as the master service node, discovers the exception in the heartbeat detection, the master service node can push the execution exception response to the exception interrupt request identifier held by microservice B2, thereby reducing the invalid waiting of the requester. For very large-scale systems, by adjusting the cluster hierarchy, the service cluster is partitioned for a second time according to specific rules, and the election process is repeated to control the number of messages forwarded by a single master service node. For scenarios with moderate service scale and a large number of messages that exceed the load range of a single primary cluster master service node, a multi-primary cluster master service node mode is adopted, consuming the response queue at the same time and exchanging messages with each other.

[0085] In the above application embodiment, the path from the target node to the initiating node is determined according to the unique identifier in the service request, so that the reply message of the service request is returned to the initiating node.

[0086] In one embodiment, an implementation of the above S201 is provided, such as Figure 5 As shown, the above “building a primary cluster and a secondary cluster in the asynchronous communication cluster according to the processing performance parameters of each service node in the asynchronous communication cluster” includes:

[0087] S501, determine multiple secondary master service nodes and multiple secondary slave service nodes in the asynchronous communication cluster according to the processing performance parameters of each service node in the asynchronous communication cluster, and construct a secondary cluster in the asynchronous communication cluster based on the secondary master service nodes and the secondary slave service nodes.

[0088] In an embodiment of the present application, an asynchronous communication cluster includes multiple service nodes, and the multiple service nodes in the asynchronous communication cluster are divided into multiple service node groups according to preset grouping information. Further, the target service node obtains the processing performance parameters of each service node in the asynchronous communication cluster. For each service node group, the performance of each service node is sorted according to the processing performance parameters of each service node in the service node group, and the service node with the best performance is determined as the secondary master server in the service node group. The other service nodes in the service node group except the secondary master service node are determined as secondary slave service nodes, so that the service node group is constructed into a secondary cluster. Optionally, the processing performance parameters can be hardware parameters of the service nodes, so that the hardware parameters are evaluated to obtain the evaluation values ​​of each service node, and further, the performance of each service node is sorted according to the evaluation values ​​of each service node.

[0089] Optionally, the service nodes in the service node group may be ranked according to their processing performance parameters, and each service node may be voted for, for example, voting in favor of the service node ranked first and voting against service nodes other than the service node ranked first.

[0090] S502, determine a primary master service node and multiple primary slave service nodes in the asynchronous communication cluster according to the processing performance parameters of each secondary master service node, and construct a primary cluster in the asynchronous communication cluster according to the primary master service node and the primary slave service node.

[0091] In the embodiment of the present application, multiple secondary main service nodes are formed into a primary cluster, and a primary main service node and a primary slave service node are determined from multiple secondary main services, and the performance of each secondary main service node is sorted according to the processing performance parameters of each secondary main service node in the primary cluster, and the secondary main service node with the best performance is determined as the primary main server in the primary cluster, and the other service nodes in the primary cluster except the primary main service node are determined as the primary slave service nodes. It should be noted that the method of constructing a primary cluster is the same as the method of constructing a secondary cluster.

[0092] In the above-mentioned application embodiment, asynchronous communication is centrally divided into a primary cluster and a secondary cluster, multi-level distribution is implemented for response messages, and the dependence on a unified intermediate agent is removed, thereby reducing the complexity of asynchronous processing. While improving the message routing efficiency, the reliability of the system is greatly improved. The primary master service node, the primary slave service node, the secondary master service node, and the secondary slave service node are determined according to the processing performance parameters of each service node, thereby improving the accuracy of the primary cluster and the secondary cluster.

[0093] In one embodiment, an implementation of the above S501 is provided, where the processing performance parameters include the priority coefficient and request response time of each historical processing request in each service node, such as Figure 6 As shown, the above “determining multiple secondary master service nodes and multiple secondary slave service nodes in the asynchronous communication cluster according to the processing performance parameters of each service node in the asynchronous communication cluster” includes:

[0094] S601, determining the waiting weight of each service node according to the priority coefficient and request response time of each historical processing request in each service node.

[0095] As an optional implementation, for each service node, the waiting weight range of the service node can be determined based on the priority coefficient of each historical processing request in the service node. Further, the waiting weight of the service node can be determined from the waiting weight range based on the request response time of each historical processing request in the service node.

[0096] As another optional implementation, the waiting weight of each service node may be determined according to the priority coefficient and request response time of each historical processing request in each service node and a preset first relationship.

[0098] In the embodiment of the present application, for each service node, the forwarding weight of each service node is determined according to the waiting weights of all service nodes in each service node group except the service node.

[0099] Optionally, a correspondence between waiting weight and forwarding weight can be established in advance, so as to determine the forwarding weight of each service node according to the waiting weight of each service node; or, the forwarding weight of each service node can be determined according to the waiting weight of each service node and a preset second relationship.

[0100] S603: Determine the service node with the highest forwarding weight in each group of service nodes of the asynchronous communication cluster as a secondary master service node, and determine the service nodes other than the secondary master service node as secondary slave service nodes.

[0101] In the embodiment of the present application, the service node with the highest forwarding weight in each group of service nodes of the asynchronous communication cluster is determined as the secondary master service node, and the service nodes other than the secondary master service node are determined as secondary slave service nodes. Optionally, the service node with the lowest forwarding weight can be removed from the secondary cluster.

[0102] In the above application embodiment, the waiting weight of the service node is determined based on the priority coefficient and the request response time, which improves the credibility of the waiting weight. Further, the forwarding weight is determined based on the waiting weight, which improves the credibility of the forwarding weight, thereby improving the accuracy of the secondary master service node and the secondary slave service node in the secondary cluster.

Further, the forwarding weight of the service node is determined according to the waiting weight of the forwarding service node. The message forwarding weight of a service node is shown in Formula 1:

[0108] in, is the waiting weight of the nth service node, and the message forwarding weight represents the number of slave nodes. The forwarding cost coefficient required to route all messages of the current cluster to other nodes. It should be noted that the greater the message forwarding weight, the smaller the election value of the current node.

[0109] In the above application embodiment, for each service node, the forwarding weight of the service node is determined according to the waiting weights of other service nodes, thereby improving the accuracy of the forwarding weight.
