Enhancement
Recently, a data corruption bug in TiCDC caused by sharing identical table schemas was discovered: pingcap/ticdc#3876. TiFlash employs a similar approach to reduce memory overhead when handling a large number of tables with identical schemas. Additional tests are needed to ensure that this mechanism does not introduce data correctness issues in TiFlash.
