Less than one month left until Percona Live. This time the Committee work was a bit unusual. Instead of having one big committee for the whole conference we had a few mini-committees, each responsible for a track. Each independent mini-committee, in turn, had a leader who was responsible for the whole process. I led the MariaDB track. In this post, I want to explain how we worked, which topics we have chosen, and why.

For MariaDB, we had seven slots: five for 50-minutes talks, two for 25-minutes talks and 19 submissions. We had to reject two out of three proposals.

The purpose of the benchmark is to see how these three solutions work on a single big server, with many CPU cores and large amounts of RAM. Both systems are massively parallel (MPP) database systems, so they should use many cores for SELECT queries.

For the benchmarks, I chose …
