--- title: RocksDB 3.2 release layout: post author: leijin category: blog redirect_from: - /blog/647/rocksdb-3-2-release/ --- Check out new RocksDB release onĀ [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
