Embodiment Construction

[0059] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, which include various details of the embodiments of the present invention to facilitate understanding and should be considered as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted from the following description for clarity and conciseness.

[0060] For chain services, the data processing process is strictly ordered, and once the order is disrupted, processing errors will occur. For example, for an account opening transaction, it needs to go through the account inspection service, the identity verification service, the customer information entry service and the bank card opening service in order to complete the acc...

Abstract

The invention discloses a data synchronization method, device and system, and relates to the technical field of computers. A specific implementation of the method includes: generating a connection request in response to the carried business service, and sending the connection request to the management cluster; judging whether the connection request belongs to a request for disconnection and reconnection, and if so, responding to the running business service Obtain the local cache data, and receive the first data sent by the management cluster to update the local cache data; otherwise, when receiving the management cluster broadcast, obtain the second data from the management cluster, and cache the second data locally for use The running business service is obtained. This embodiment enables the business service to still provide uninterrupted service when the link is disconnected and reconnected.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a data synchronization method, device and system. Background technique [0002] In the banking industry, many business services are completed under a service-oriented architecture (SOA architecture). That is, a business process calls different service parties in turn through the chain service call. When the last service party is successfully called, the entire business process is completed. In this process, each server on the chain relies on the data of the previous server, that is, the server on the chain service needs to obtain data from the previous server. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: [0004] The existing chained service calls, once the chain disconnection and reconnection occurs, will cause the service to stagnate.
