Summary: Currently it is not possible to change bloom filter config without restart the db, which is causing a lot of operational complexity for users. This PR aims to make it possible to dynamically change bloom filter config. Closes https://github.com/facebook/rocksdb/pull/3601 Differential Revision: D7253114 Pulled By: miasantreble fbshipit-source-id: f22595437d3e0b86c95918c484502de2ceca120c
