RocksDB, InnoDB and TokuDB vs sysbench
+0 Vote Up -0Vote Down

This compares RocksDB and InnoDB storage engines using sysbench and extends the results I shared yesterday. I continue to get great performance from MyRocks and this is a bonus as my motivation for using it is better storage efficiency.

tl;dr - MyRocks is usually equal to or faster than InnoDB on these tests

The test server for InnoDB and RocksDB has 2 sockets, 24 cores (48 HW threads), 256G of …

Measuring Docker IO overhead
+0 Vote Up -0Vote Down

This will be another post on using Percona Server via a Docker image. I want to follow up on my previous post regarding CPU/Network overhead in Docker “Measuring Percona Server Docker CPU/network overhead” by measuring  if there is any docker IO overhead on operations.

Comment on Life at Pythian as a MySQL DBA by Natalia
+0 Vote Up -0Vote Down

Hi Derek, thanks for sharing with us this post, from my perspective it was really helpful.

At the moment I work freelance but I am very interested in a job position for Pythian.

Do you know if there´s any job position for Windows Admin?
