Vardhan 87a21d08fe Add an option to trigger flush when the number of range deletions reach a threshold (#11358 An error occurred ) ... Summary: Add a mutable column family option `memtable_max_range_deletions`. When non-zero, RocksDB will try to flush the current memtable after it has at least `memtable_max_range_deletions` range deletions. Java API is added and crash test is updated accordingly to randomly enable this option. Pull Request resolved: https://github.com/facebook/rocksdb/pull/11358 Test Plan: * New unit test: `DBRangeDelTest.MemtableMaxRangeDeletions` * Ran crash test `python3 ./tools/db_crashtest.py whitebox --simple --memtable_max_range_deletions=20` and saw logs showing flushed memtables usually with 20 range deletions.
