Percona MyRocks Introduction
============================

`MyRocks <http://myrocks.io>`_ is a storage engine
for `MySQL <https://www.mysql.com>`_ based on `RocksDB <http://rocksdb.org/>`_,
an embeddable, persistent key-value store.
*Percona MyRocks* is an implementation
for `Percona Server <https://www.percona.com/software/percona-server>`_.

The RocksDB store is based on the log-structured merge-tree (or LSM tree).
It is optimized for fast storage
and combines outstanding space and write efficiency
with acceptable read performance.
As a result, MyRocks has the following advantages
compared to other storage engines,
if your workload uses fast storage, such as SSD:

* Requires less storage space
* Provides more storage endurance
* Ensures better IO capacity
