Method and device for testing load replay between heterogeneous databases

The embodiment of the invention provides a load replay test method and device between heterogeneous databases, which can be used in the technical field of artificial intelligence, and the method comprises the following steps: obtaining a recording load statement of a source database; load conversion is conducted on the recorded load statement, target statement expression of a target database is generated, and the source database and the target database are heterogeneous databases; generating a replay time limit according to the recorded load statement and a preset user configuration parameter; and performing load replay on the target database according to the replay time limit and the target statement expression, and generating a load replay test result, so as to be independent of different types of databases, support load replay test and replay time limit adjustment between heterogeneous databases, and replace the target statement expression to the target database within the replay time limit at different ra
