RocksDB is excellent! MyRocks (https://mariadb.com/kb/en/library/about-myrocks-for-mariadb/ https://mariadb.com/kb/en/library/about-myrocks-for-mariadb/), a storage backend for MariaDB based on RocksDB was so extremely promising for massively cutting back on disk thruput - we never flipped it to being used on the primary servers because it was extremely beta back then. I should write a few emails and check up on that - if I recall correctly it was a roughly 5x reduction on disk writes compared to INNODB.
