MyRocks is an open source storage engine that was originally developed by
Facebook.

MyRocks has been extended by the MariaDB engineering team to be a pluggable
storage engine that you use in your MariaDB solutions. It works seamlessly
with MariaDB features. This openness in the storage layer allows you to use the
right storage engine to optimize your usage requirements, which provides
optimum performance. Community contributions are one of MariaDB’s greatest
advantages over other databases. Under the lead of our developer Sergey
Petrunia, MyRocks in MariaDB is constantly being merged with upstream MyRocks
from Facebook.
