RocksDB 3.2 release post leijin blog
/blog/647/rocksdb-3-2-release/

Check out new RocksDB release on GitHub!

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
