This gives you the ability to rapidly spin up a cluster for experimentation, performance testing, or even production use on Google Compute Engine virtual machines. What is Percona XtraDB Cluster?

Q&A: Percona XtraDB Cluster as a MySQL HA solution for OpenStack

Thanks to all who attended my Nov. 12 webinar titled, “Percona XtraDB Cluster as a MySQL HA Solution for OpenStack.” I had several questions which I covered at the end and a few that I didn’t.

OpenStack MySQL HA Solution = Percona XtraDB Cluster: Webinar

MySQL is the most popular and widely used open source database on the planet. OpenStack is fast evolving as the defacto open source cloud platform. OpenStack services such as Nova (Compute), Cinder (Storage), Neutron (Networking), to name just a few, all use MySQL as default datastore. OpenStack is a cloud platform and therefore needs to […]

Percona XtraDB Cluster: How to run a 2-node cluster on a single server

I reckon there’s little sense in running 2 or more Percona XtraDB Cluster (PXC) nodes in a single physical server other than for educational and testing purposes – but doing so is still useful in those cases.

I asked to describe what they are seeing, and as […]

Multi-Valued INSERTs, AUTO_INCREMENT & Percona XtraDB Cluster

A common migration path from standalone MySQL/Percona Server to a Percona XtraDB Cluster (PXC) environment involves some measure of time where one node in the new cluster has been configured as a slave of the production master that the cluster is slated to replace. In this way, the new cluster acts as a slave of […]

How to calculate the correct size of Percona XtraDB Cluster’s gcache

When a write query is sent to Percona XtraDB Cluster all the nodes store the writeset on a file called gcache. By default the name of that file is galera.cache and it is stored in the MySQL datadir. This is a very important file, and as usual with the most important variables in MySQL, the […]
