Summary: When a memtable is flushed, it will validate number of entries it reads, and compare the number with how many entries inserted into memtable. This serves as one sanity c\ heck against memory corruption. This change will also allow more counters to be added in the future for better validation. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8288 Test Plan: Pass all existing tests Reviewed By: ajkr Differential Revision: D28369194 fbshipit-source-id: 7ff870380c41eab7f99eee508550dcdce32838ad
