Alexander Rubin (VirtualHealth) delivers the talk, "Opensource Column Store Databases: MariaDB ColumnStore vs. ClickHouse", on DAY 1 of the Percona Live Open Source Database Conference 2019, 5/29, at Austin, TX.

Running an analytical (OLAP) workload on top of MySQL can be slow and painful. A specifically designed storage format ("Column Store") can significantly improve analytical queries' performance. There are a number of opensource column store databases around. In this talk, I will focus on two of them which can support MySQL protocol: MariaDB ColumnStore and ClickHouse.

I will show some realtime benchmarks and use cases, and demonstrate how MariaDB ColumnStore and ClickHouse can be used for typical OLAP queries. I will also do a quick demo.
