Abstract
The disclosure discloses a transaction processing method, a processing node, and a central node. The method includes: receiving, by the processing node in the cluster, global snapshot information according to a preset time interval, where the global snapshot information includes a transaction identifier of a running transaction in a cluster; storing the received global snapshot information in a cache; and processing the transaction according to the global snapshot information stored in the cache. In the transaction processing method, a central node in a cluster sends latest global snapshot information to each processing node according to a preset time interval, so that the processing node can store the global snapshot information. When applying for global snapshot information during transaction processing, the processing node does not need to obtain latest snapshot information from the central node. Therefore, network overheads can be reduced, and transaction processing efficiency can be improved.
