Embodiment 2

[0079] According to another embodiment of the present invention, a method for synchronizing memory state data is also provided, image 3 It is a flow of a method for synchronizing memory state data according to an embodiment of the present invention Figure II ,Such as image 3 As shown, the process includes the following steps:

[0080] Step S302, the message middleware platform creates the same memory state data topic subscribed by all application service nodes in the distributed application service;

[0081] Specifically, the message middleware platform receives subscription request messages sent by all application service nodes (including the first application service node and other application service nodes), and creates simultaneous An in-memory state data topic.

[0082] Step S304, the message middleware platform forwards the synchronization message sent by the first application service node to other application service nodes subscribed to the memory state data topic...

Abstract

The invention provides a memory state data synchronization method and device. The method comprises the steps that a first application service node and other application service nodes in a distributedapplication service subscribe to the same memory state data theme of a message middleware platform, and the other application service nodes are all application service nodes except the first application service node in the distributed application service; the first application service node performs memory state data synchronization with the other application service nodes based on the memory statedata theme through the message middleware platform. According to the method and the device, the problems of non-persistence of subscription relation and non-persistence of messages in data synchronization of cluster services coordinated by redis in related technologies can be solved, memory state data synchronization among distributed application services is realized through themes of a message middleware platform, so that a message synchronization function is stable, and messages can be persisted.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for synchronizing memory state data. Background technique [0002] In order to ensure the stability of background software services, background services need to be deployed in a distributed cluster to provide undifferentiated background services for requests. Each service process needs to maintain its own memory state data, and the random distribution of requests will cause each service The inconsistency of process memory state data will cause business exceptions. In order to reduce the risk of business anomalies, there needs to be a method to synchronize the memory status data of each process in the background service cluster in real time, so as to maintain the consistency of the memory status data of each service. [0003] For data synchronization between distributed application services, shared memory redis is used in related technologies to achieve: ...
