Description

Technical Field

[0001] The present invention relates to the technical field of data subscription, and in particular to a data subscription method, device, electronic device, storage medium and program product. Background Art

[0002] With the development of digital and intelligent technologies, enterprises and organizations are facing a large number of real-time data processing needs. The publish-subscribe model is widely used due to its flexibility and scalability, but problems such as data synchronization delays, sharing difficulties and performance bottlenecks limit system stability.

[0003] Enterprise Service Bus (ESB) data bus technology is a common solution that integrates multiple services and provides a unified data exchange platform to achieve data flow between different systems. In particular, ESB generally adopts full data subscription technology, that is, no matter what changes occur in the data, it will be sent to all downstream services that subscribe to the data in real time. Although this method ensures instant synchronization of data, when faced with massive data, especially in scenarios with extremely large business data traffic, full subscription often leads to a decrease in the processing speed of the subscription service, service jams, and even a service avalanche effect caused by a single business exception. In addition, in order to cope with traffic peaks, related technologies often rely on increasing hardware resources or optimizing software architecture to improve processing capabilities, but these measures often lack flexibility and cannot dynamically adjust resource allocation according to real-time traffic, which can easily lead to performance bottlenecks and request response delays during peak traffic periods.

[0031] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The following describes a data subscription method, a computer-readable storage medium, a computer program product, an electronic device, a data subscription apparatus, and a data subscription system according to embodiments of the present invention with reference to the accompanying drawings.

[0033] Before introducing the data subscription method and device of the present invention, the data subscription of the present invention is first explained accordingly. Specifically, the data subscription method and device are applied to a resource allocation pipeline, and the resource allocation pipeline includes multiple service channels. Resources are shared between multiple service channels, so that when a service channel fails, the resources on the failed service channel can be allocated to other service channels, and when the number of data subscription services of multiple service channels is greater than the upper limit of the total capacity of the multiple service channels, a new resource allocation pipeline can be set to allocate part of the data subscription services to the new resource allocation pipeline, thereby enhancing the flexibility and reliability of the system and improving the utilization of resources. The data input end of the resource allocation pipeline is connected to the publishing system, and the data output end of the resource allocation pipeline is connected to the subscription system. For example, Figure 1 As shown, the resource allocation pipeline can be preferably an SDP (Service Data Plane) data pipeline, and a data subscription model 100 is provided. The data subscription model 100 includes an SDP data pipeline, and the SDP data pipeline includes multiple business channels, such as business channel 1, business channel 2 and business channel 3. Business channel 1, business channel 2 and business channel 3 all include MQ clusters and application service groups. The data input end of the resource allocation pipeline is connected to a publishing system, such as a first publishing system, a second publishing system, a third publishing system and a fourth publishing system, and the data output end of the resource allocation pipeline is connected to a subscription system, such as a first subscription system, a second subscription system, a third subscription system and a fourth subscription system.

[0034] Figure 2 It is a flowchart of a data subscription method according to an embodiment of the present invention.

[0035] Specifically, in some embodiments of the present invention, Figure 2 As shown, the data subscription method includes:

[0036] S101, obtaining a subscription request sent by a subscription system.

[0037] Specifically, in this embodiment, Figure 1 As shown, the subscription system includes a first subscription system, a second subscription system, a third subscription system and a fourth subscription system, etc., and the subscription request sent by the subscription system can be obtained through a preset interface or protocol. The subscription request includes the number and type of data subscription services.

[0038] S102: upon receiving a subscription request, determining a target service channel from a plurality of service channels.

[0039] Specifically, in this embodiment, Figure 1 As shown, if the received service request is to subscribe to the first data subscription service and the second data subscription service, service channel 1 can be determined as the target service channel; if the received service request is to subscribe to the fourth data subscription service and the fifth data subscription service, service channel 2 can be determined as the target service channel.

[0040] S103, sending the data subscription service to the subscription system through the target service channel to complete the data subscription, wherein the data subscription service is published through the publishing system.

[0041] Specifically, in this embodiment, Figure 1 As shown, the subscription system includes a first subscription system, a second subscription system, a third subscription system and a fourth subscription system, etc. If the first subscription system sends a subscription request to subscribe to a first data subscription service, service channel 1 can be determined as the target service channel, and then the first data subscription service can be sent to the first subscription system through service channel 1 to complete the data subscription, wherein the data subscription service is published through a publishing system, and the publishing system includes a first publishing system, a second publishing system, a third publishing system and a fourth publishing system, etc. The first data subscription service can be published by the first publishing system, which is not specifically limited here.

[0042] Furthermore, in some embodiments of the present invention, the resources of each service channel include a data processing cluster and an application service group, and the data subscription service is sent to the subscription system through the target service channel, including: using the data processing cluster corresponding to the target service channel to perform peak shaving and valley filling processing on the data subscription service; using the application service group corresponding to the target service channel to perform storage processing, comparison processing and outbound subscription processing on the data subscription service.

[0043] Specifically, in this embodiment, the data processing cluster may preferably be an MQ (Message Queue) cluster, such as Figure 1As shown, the MQ cluster includes an MQ1 cluster and an MQ2 cluster. When the target business channel is business channel 1, after the first publishing system publishes the first data subscription service to business channel 1, the MQ1 cluster in business channel 1 performs peak shaving and valley filling processing on the first data subscription service, and adopts an application service group to save, compare and send out subscription processing on the first data subscription service after the peak shaving and valley filling processing. It should be noted that the application service group includes a first application service group, a second application service group and a third application service group, and then the first data subscription service can be sequentially saved through the first application service group, compared through the second application service group, and sent out subscription processing through the third application service group.

[0044] It should be noted that the MQ cluster receives data subscription services from the publishing system and performs peak shaving and valley filling processing according to the system load, thereby avoiding performance bottlenecks under high concurrency conditions. The data subscription services after peak shaving and valley filling processing are passed to the application service group for preservation processing. This step ensures that the data is safely stored in the system for subsequent use. Secondly, the application service group compares the saved data to check the integrity and consistency of the data, which helps to ensure the accuracy and reliability of the data. Finally, the application service group sends the processed data to the subscription system to complete the data subscription business process.

[0045] Furthermore, in some embodiments of the present invention, fault isolation settings are performed between different service channels, between different data processing clusters, and between different application service groups.

[0046] Specifically, in this embodiment, Figure 1 As shown, business channel 1, business channel 2 and business channel 3 are isolated from each other, and the MQ clusters and application service groups in business channel 1, business channel 2 and business channel 3 are also isolated, which can improve the security and stability of the system, thereby providing users with more efficient and reliable data subscription services.

[0047] Furthermore, in some embodiments of the present invention, different data subscription services are respectively bound to different service channels, and a target service channel is determined from multiple service channels, including: determining the service channel bound to the data subscription service as the target service channel; when a service channel bound to the data subscription service fails, obtaining the idleness of each service channel in other service channels; and determining the target service channel from other service channels based on the idleness.

[0048] Specifically, in this embodiment, Figure 1As shown, the first data subscription service, the second data subscription service and the third data subscription service are bound to service channel 1, the fourth data subscription service, the fifth data subscription service and the sixth data subscription service are bound to service channel 2, and service channel 3 can be bound to one or more of the other data subscription services, thereby improving the flexibility and scalability of the system and providing users with more efficient and reliable data subscription services. Figure 3 As shown, service channel 3 can be bound to one or more services in other data subscription services. If service channel 3 fails, the idleness of service channel 1 and service channel 2 can be obtained. If the idleness of service channel 2 is greater than that of service channel 1, service channel 2 can be determined as the target service channel, thereby improving the reliability and stability of the system and enhancing the fault tolerance of the system. The idleness refers to the proportion of resources that are currently not used in the service channel.

[0049] Furthermore, in some embodiments of the present invention, when it is obtained that a new service channel exists in the resource allocation pipeline, resource sharing between the new service channel and multiple service channels is set.

[0050] Specifically, in this embodiment, when the congestion degree of multiple service channels is greater than the preset congestion degree, or the number of data subscription services is greater than the total capacity upper limit of multiple service channels, a new service channel is set in the resource allocation pipeline, for example, Figure 4 As shown, when business channel 1, business channel 2 and business channel 3 cannot complete the resource allocation processing for the data subscription service, a new application service group and a new MQ cluster are added to construct business channel 4, and then business channel 4 assists business channel 1, business channel 2 and business channel 3 in resource allocation processing for the data subscription service. At this time, resources are shared between business channel 4 and business channel 1, business channel 2 and business channel 3. The congestion degree refers to the congestion condition or the degree of reduced efficiency of the business channel when processing the data subscription service. The congestion degree can be measured by the average processing time of a single data subscription service of the business channel and / or the number of data subscription services backlogged in the waiting queue. For example, if the number of data subscription services backlogged in the waiting queue is greater than 100, it means that the congestion degree of multiple business channels is greater than the preset congestion degree.

[0051] It should be noted that if Figure 4As shown in the figure, when business channel 1, business channel 2 and business channel 3 cannot complete the resource allocation processing for the data subscription business, the new MQ cluster in the expanded business channel 4 is the MQ3 cluster, which is different from the MQ clusters in business channel 1, business channel 2 and business channel 3. The MQ cluster in business channel 1 is the MQ1 cluster, and the MQ clusters in business channel 2 and business channel 3 are the MQ2 cluster. It should be noted that business channel 2 and business channel 3 share the MQ2 cluster to save costs. By introducing a new business channel and its supporting MQ cluster, the existing MQ cluster is effectively supplemented and optimized, the overall performance and scalability of the system are improved, and the long-term operating costs are reduced.

[0052] Furthermore, in some embodiments of the present invention, the service channel is determined according to the characteristics of the data subscription service, wherein the characteristics of the data subscription service include at least one parameter of the number, change frequency, message size and importance of the data subscription service.

[0053] Specifically, in this embodiment, the service channel is determined according to the characteristics of the data subscription service. For example, the service channel can be divided into at least one core service channel and at least one ordinary service channel according to the importance of the data subscription service. The service channel can be divided into at least one large message channel and at least one small message channel according to the message size of the data subscription service, wherein a small message is a message less than or equal to one hundred bytes, and a large message is a message greater than one hundred bytes. It should be noted that this definition is not absolute and fixed, and it is only used as a reference standard in the embodiment of the present invention. In addition, the service channel can also be determined according to at least one parameter among the number, change frequency, message size and importance of the data subscription service.

[0054] In summary, according to the data subscription method of an embodiment of the present invention, a subscription request sent by a subscription system is obtained, and when the subscription request is received, a target business channel is determined from multiple business channels, so as to send the data subscription service to the subscription system through the target business channel to complete the data subscription, wherein the data subscription service is published through the publishing system. Therefore, through the isolation and resource allocation of business channels, the stability and response speed of the subscription service can be improved, thereby optimizing the data processing process, reducing data synchronization delays, and realizing the sharing and integration of business master data.

[0055] Figure 5 is a block diagram of a data subscription device according to an embodiment of the present invention.

[0056] Specifically, the data subscription device is applied to a resource allocation pipeline, which includes multiple business channels. Resources are shared between the multiple business channels. The data input end of the resource allocation pipeline is connected to the publishing system, and the data output end of the resource allocation pipeline is connected to the subscription system. The data subscription device 200 includes an acquisition module 10, a selection module 20 and a processing module 30.

[0057] Among them, the acquisition module 10 is used to obtain the subscription request sent by the subscription system; the selection module 20 is used to determine the target business channel from multiple business channels when the subscription request is received; the processing module 30 is used to send the data subscription service to the subscription system through the target business channel to complete the data subscription, wherein the data subscription service is published through the publishing system.

[0058] In some embodiments of the present invention, the resources of each service channel include a data processing cluster and an application service group. The data subscription service is sent to the subscription system through the target service channel. The processing module 30 is also used to use the data processing cluster corresponding to the target service channel to perform peak shaving and valley filling processing on the data subscription service; and use the application service group corresponding to the target service channel to perform storage processing, comparison processing and outbound subscription processing on the data subscription service.

[0059] In some embodiments of the present invention, fault isolation settings are performed between different service channels, between different data processing clusters, and between different application service groups.

[0060] In some embodiments of the present invention, different data subscription services are respectively bound to different service channels, and a target service channel is determined from multiple service channels. The processing module 30 is also used to determine the service channel bound to the data subscription service as the target service channel; when a service channel bound to the data subscription service fails, the idleness of each service channel in other service channels is obtained; and the target service channel is determined from other service channels based on the idleness.

[0061] In some embodiments of the present invention, the processing module 30 is further configured to set resource sharing between the newly added service channel and multiple service channels when it is obtained that a newly added service channel exists in the resource allocation pipeline.

[0062] In some embodiments of the present invention, the processing module 30 is further used to set a new service channel in the resource allocation pipeline when the congestion degree of multiple service channels is greater than a preset congestion degree, or the number of data subscription services is greater than the total capacity upper limit of multiple service channels.
