This topic describes the application scenarios of performance assessment.
When you migrate data from an Oracle database to OceanBase Database, assess the performance differences of identical SQL statements in OceanBase Database and the Oracle database so that you can optimize the performance accordingly.
When you upgrade OceanBase Database, assess the performance differences between the two versions of OceanBase Database.
During performance assessment, all traffic is replayed based on the real traffic and queries per second (QPS) to simulate the real environment.
