Performance Evaluation of SST Data Transfer: Without Encryption (Part 1)

SST Data Transfer

In this blog, we’ll look at evaluating the performance of an SST data transfer without encryption.
A State Snapshot Transfer (SST) operation is an important part of Percona XtraDB Cluster. It’s used to provision the joining node with all the necessary data. There are three methods of SST operation available: mysqldump, rsync, xtrabackup. The most […]

State Snapshot Transfer (SST) at a glance
PXC uses a protocol called State Snapshot Transfer to provision a node joining an existing cluster with all the data it needs to synchronize.  This is analogous to cloning a slave in asynchronous replication:  you take a full backup of one node and copy it to the new […]

Bypassing SST in Percona XtraDB Cluster with binary logs

In my previous post, I used incremental backups in Percona XtraBackup as a method for rebuilding a Percona XtraDB Cluster (PXC) node without triggering an actual SST. Practically this reproduces the SST steps, but it can be handy if you already had backups available to use.
In this post, I want to present another methodology […]
