| description | The invention discloses a cross-engine transaction processing method which can be applied to a database system, the database system at least can comprise a first database engine and a second database engine, and the method comprises the steps of obtaining time sequence information, wherein the time sequence information can indicate that the first sub-transaction of the first cross-engine transaction is not later than the first sub-transaction of the second cross-engine transaction to execute the target operation, the target operation can access data in the first database engine, and according to the obtained time sequence information, the first data accessed by the second sub-transaction of the first cross-engine transaction in the second database engine can be determined not to be later than the first data accessed by the second sub-transaction of the second cross-engine transaction in the second database engine in time sequence, so that the data accessed by the two cross-engine transactions are kept consist |
