| 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
