Summary: Previously it only applied to block-based tables generated by flush. This restriction was undocumented and blocked a new use case. Now compression sampling applies to all block-based tables we generate when it is enabled. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8105 Test Plan: new unit test Reviewed By: riversand963 Differential Revision: D27317275 Pulled By: ajkr fbshipit-source-id: cd9fcc5178d6515e8cb59c6facb5ac01893cb5b0
