Database used for Parity

Question

Specific to Geth the database used is LevelDB. But what is the database used for parity?

Answer 1

I'm one of parity devs. We use Rocksdb. It's a key-value database developed by Facebook. We chose it mostly because of it's performance. In our benchmarks it was faster than LevelDB

From their webpage:

RocksDB is optimized for fast, low latency storage such as flash drives and high-speed disk drives. RocksDB exploits the full potential of high read/write rates offered by flash or RAM.

Answer 2

The answer here is slightly out of date. Parity has migrated to use blooms db which is an implementation of a Bloom Filter to reduce overall disk reads.

The blooms are a db layer before the kvdb RocksDB.
