fragmented data file performance

In this blog post, we’ll discuss how we’ve improved TokuDB and PerconaFT fragmented data file performance. Through our internal benchmarking and some user reports, we have found that with long term heavy write use TokuDB/PerconaFT performance can degrade significantly on large data files. Using smaller node sizes makes the problem worse (which is one of […]

TokuDB impacts InnoDB performance

This blog discusses how TokuDB impacts InnoDB performance when the two run in the same environment. You would think MySQL storage engines are fairly independent of each other, even in the same environment. Enabling one, or changing its configuration, logically should have no impact on the performance of other engines (such as InnoDB) when they […]
