Handling long duration SST(timeout) in PXC with systemd

In this blog post, We will be explaining about the timeouts in SST on systemd implementation which we faced recently in Percona XtraDB Cluster  during our Consulting with a client. State Snapshot Transfers (SST) refers to complete data sync from one of the nodes from the cluster to the joining node.

SST will happen for one or more reasons listed below.

  1. Initial sync to join a node to cluster.
  2. Node is out of cluster and lost its ability to join back due to data corruption or inconsistencies and also when the node went far behind the node, …

Enterprises choose Galera Cluster. Read why.

“Our three megastores’ and webshop’s combined revenue was 432 million euros in the year 2017. Galera Cluster has been the cornerstone of the system, secured our sales and supported our growth.”

“MySQL master/slave setup was just too fragile and needed regular work to fix each time the slave got out of sync. Now with Galera we’ve found that even if we take a node offline for a while, it re-syncs automatically and without intervention.”

“The big plus is that all nodes have exact the same information, and no node is running for even a fraction of a second behind. This will also mean that no information will be lost!”

Bulgarian National Lottery chooses Galera Cluster

“We wanted a solution which was backward compatible with our frameworks, as we have used mainly MySQL, which was reliable and nearly 100% data consistent.  If our application were to execute a commit and receive a successful response, we needed a 100% guarantee that we have rows of data in our database — and for more than that one instance.”

There were many options E-CARD explored. “First, we tried MySQL NDB Cluster. That was a very frustrating experience. After that we tried a few other plugins and extensions of MySQL, but they weren’t complete solutions. At the end of this process, we found Galera with MySQL. It responded to our needs nearly 100% of the time.”
