TokuDB/PerconaFT fragmented data file performance improvements
+0 Vote Up -0Vote Down

In this blog post, we’ll discuss how we’ve improved TokuDB and PerconaFT fragmented data file performance.

TokuDB Read Free Replication : not implemented in MariaDB!

I) Why using TokuDB?

I have been playing with TokuDB since 2013. Although it’s a really good storage engine, it’s sometimes full of surprises.

Initially I migrated one of my customer from InnoDB to TokuDB because it was solving all their issues : their DB has been growing to more then 1TB, and they were facing insert performances issues.

After the migration, there DB size dropped to 100GB which was really amazing, without loss in performances compared to InnoDB, and way better insert performances.
