Abstract

The invention discloses a method, a device and a medium for ensuring final data consistency of distributed transactions, the method comprises the following steps: acquiring a business request, acquiring a service set formed by each service associated with the business request, wherein the server set at least comprises two services; obtaining a parameter of each service related to the business request to obtain a parameter subset corresponding to the service, and obtaining a parameter set corresponding to the service set based on the parameter subset corresponding to each service in the serviceset; generating an idempotent task according to the parameter set, wherein the idempotent task is used for performing idempotent operation on each parameter in the parameter set; and executing the idempotent task, and returning an execution result of the idempotent task. According to the method, the time required for achieving the final data consistency state is remarkably shortened, and the timedelay is reduced while it is ensured that the distributed transaction is executed at a high success rate.

Description

technical field [0001] The invention relates to the field of distributed transactions, in particular to a method, device and medium for ensuring final data consistency of distributed transactions. Background technique [0002] With the increase of business complexity, more and more businesses need to rely on the interactive realization of different nodes in the distributed system, and different nodes can provide different services. In a distributed system, each node is physically independent from each other and communicates and coordinates through the network. However, independent nodes cannot accurately know the transaction execution status of other nodes, so it is difficult to guarantee the final data consistency between each node. The final data consistency means that with the migration of time, the The corresponding data is always changing in the direction of convergence, so as to reach the final consistent state. In the prior art, the schemes to ensure the final data ...
