Check out new RocksDB release on [GitHub](https://github.com/facebook/rocksdb/releases/tag/rocksdb-3.2)!
|
||
|
||
New Features in RocksDB 3.2:
|
||
|
||
|
||
|
||
|
||
* PlainTable now supports a new key encoding: for keys of the same prefix, the prefix is only written once. It can be enabled through encoding_type paramter of NewPlainTableFactory()
|
||
|
||
|
||
* Add AdaptiveTableFactory, which is used to convert from a DB of PlainTable to BlockBasedTabe, or vise versa. It can be created using NewAdaptiveTableFactory()
|
||
|
||
|
||
Public API changes:
|
||
|
||
|
||
* We removed seek compaction as a concept from RocksDB
|
||
|
||
|
||
* Add two paramters to NewHashLinkListRepFactory() for logging on too many entries in a hash bucket when flushing
|
||
|
||
|
||
* Added new option BlockBasedTableOptions::hash_index_allow_collision. When enabled, prefix hash index for block-based table will not store prefix and allow hash collision, reducing memory consumption
