MyRocks Troubleshooting

Please join Percona’s Principal Technical Services Engineer, Sveta Smirnova, Senior Software Engineer, George Lorch, MariaDB's Query Optimizer Developer Sergei Petrunia and Facebook's Database Engineer Yoshinori Matsunobu as they present “MyRocks Troubleshooting” on March 30, 2017 at 11:00 am PDT / 2:00 pm EDT (UTC-7).

MyRocks is an alternative storage engine designed for flash storage. It provides great write workload performance and space efficiency. Like any other powerful engine, it has its own specific configuration scenarios that require special troubleshooting solutions.

We will discuss how to deal with:

- Data corruption issues
- Inconsistent data
- Locks
- Slow performance

We will use well-known instruments and tools, as well as MyRocks-specific tools, and show how they work with the MyRocks storage engine.
