This also impacts the default block cache when the user doesn't explict provide one. +* Change the default of delayed slowdown value to 16MB/s and further increase the L0 stop condition to 36 files. + +### New Features +* Added new overloaded function GetApproximateSizes that allows to specify if memtable stats should be computed only without computing SST files' stats approximations. +* Added new function GetApproximateMemTableStats that approximates both number of records and size of memtables. +* (Experimental) Two-level indexing that partition the index and creates a 2nd level index on the partitions. The feature can be enabled by setting kTwoLevelIndexSearch as IndexType and configuring index_per_partition. + +### Bug Fixes +* RangeSync() should work if ROCKSDB_FALLOCATE_PRESENT is not set +* Fix wrong results in a data race case in Get() +* Some fixes related to 2PC. +* Fix several bugs in Direct I/O supports. +* Fix a regression bug which can cause Seek() to miss some keys if the return key has been updated many times after the snapshot which is used by the iterator. |
