Percona, in collaboration with Facebook, is proud to announce the first experimental release of MyRocks in Percona Server for MySQL 5.7, with packages.
Now in September 2017, we are pleased to announce the first full experimental release of MyRocks with packages for Percona Server for MySQL 5.7.19-17.
The basis of the MyRocks storage engine is the RocksDB key-value store, which is a log-structured merge-tree (or LSM). It uses much less space, and has a much smaller write volume (write amplification) compared to a B+ tree database implementation such as InnoDB. 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
Percona MyRocks is distributed as a separate package that can be enabled as a plugin for Percona Server for MySQL 5.7.19-17.
WARNING: Percona MyRocks is currently considered experimental and is not yet recommended for production use.
We are providing packages for most popular 64-bit Linux distributions:
- Debian 8 (“jessie”)
- Debian 9 (“stretch”)
- Ubuntu 14.04 LTS (Trusty Tahr)
- Ubuntu 16.04 LTS (Xenial Xerus)
- Ubuntu 16.10 (Yakkety Yak)
- Ubuntu 17.04 (Zesty Zapus)
- Red Hat Enterprise Linux or CentOS 6 (Santiago)
- Red Hat Enterprise Linux or CentOS 7 (Maipo)
Installation instructions can be found here.
Due to the differences between Facebook MySQL 5.6.35 and Percona Server for MySQL 5.7, there are some behavioral differences and additional limitations. Some of these are documented here.
We encourage you to install and experiment with MyRocks for Percona Server for MySQL and join the discussion here.
Any issues that you might find can be searched for and reported here.
We thank the RocksDB and MyRocks development teams at Facebook for providing the foundation and assistance in developing MyRocks for Percona Server for MySQL. Without their efforts, this would not have been possible.
