### Public API Change
|
|
* NewLRUCache() will determine number of shard bits automatically based on capacity, if the user doesn't pass one. 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.

|
* 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.
|
|
