High-load clusters and desynchronized nodes on Percona XtraDB Cluster

There can be a lot of confusion and lack of planning in Percona XtraDB Clusters in regards to nodes becoming desynchronized for various reasons.  This can happen a few ways:

When I say “desynchronized” I mean a node that is permitted to build up a potentially large wsrep_local_recv_queue while some operation is happening.  For example a node taking a backup would set wsrep_desync=ON during the backup and potentially fall behind …

Database Virtualization, What it Really Means


This is a response to a blog postby analyst and marketing consultant Curt Monash.


Originally virtualization meant running one operating system in a window inside of another operating system, e.g. running a Linux on a Windows machine using Microsoft Virtual PC or VMWare. Then virtualization evolved to mean slicing a single server into many for more granular resource allocation (Curt’s ex uno plures, translated: out of one, many). It has since expanded to include e pluribus unum (from many, one) and e pluribus ad pluribus (from many to many). This is evidenced in the use of the term “virtualization” to create the compound words: server virtualization, storage virtualization, network virtualization and now database virtualization.
