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.

Would you still use that database today? – errata Mar 05 '19 at 05:32

@errata They are working on new ParityDB, which should replace it, so you can guess ;) https://github.com/paritytech/parity-db – Tharok Jan 03 '22 at 20:28

The answer here is slightly out of date.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.
