In this blog, we’ll discuss how the Percona XtraDB Cluster threading model works.

Percona XtraDB Cluster (PXC) creates a different set of threads to service its operations. These threads are in addition to existing MySQL threads. Let’s understand what these threads are and how they’re used. There are three main groups of threads:

1. Applier thread(s)
   1. Applier threads are meant to apply write-sets that the node receives from other nodes (through cluster). (write-message is directed through

That machine was shared with many other users and there was only an old python version already installed on the machine. After a bit of search and trial, I was able to install a newer version of python on this machine to my local directory.
