Summary: - Changed MergeOperator, CompactionFilter, and CompactionFilterFactory into Customizable classes. - Added Options/Configurable/Object Registration for TTL and Cassandra variants - Changed the StringAppend MergeOperators to accept a string delimiter rather than a simple char. Made the delimiter into a configurable option - Added tests for new functionality Pull Request resolved: https://github.com/facebook/rocksdb/pull/8481 Reviewed By: zhichao-cao Differential Revision: D30136050 Pulled By: mrambacher fbshipit-source-id: 271d1772835935b6773abaf018ee71e42f9491af
