TokuDB/PerconaFT fragmented data file performance improvements

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 our performance tuning recommendations when you have faster storage). The problem manifests as low CPU utilization, a drop in overall TPS and high client response times during prolonged checkpointing.

This post explains a little about how PerconaFT structures dictionary files and where the current implementation breaks down. Hopefully, it explains the nature of the issue, and how our solution helps addresses it. It also provides some contrived benchmarks that prove the solution.
