HyperDB

HyperDB is an advanced database class that supports replication, failover, load balancing, and partitioning.

Download Version

HyperDB is a very advanced database class that replaces a few of the WordPress built-in database functions. The main differences are: * HyperDB can be connect to an arbitrary number of database servers, * HyperDB inspects each query to determine the appropriate database.

It supports:

  • Read and write servers (replication)
  • Configurable priority for reading and writing
  • Local and remote datacenters
  • Private and public networks
  • Different tables on different databases/hosts
  • Smart post-write master reads
  • Failover for downed host
  • Advanced statistics for profiling

It is based on the code currently used in production on WordPress.com with many MySQL servers spanning multiple datacenters.
