  • Status: Proposed
» Description
DB_Virtual allows you to set up a single master and N nodes to balance traffic across multiple DB servers. Compatible with PEAR DB's API. It sends 100% of all manipulation queries to the master node and then uses weighted round robin scheduling to balance queries across all of the nodes.

    Updated to the latest version of the package (0.0.7). Updated the package source file as well. Changes include:

    * Fixed a bug in DB_Virtual::autoCommit() that wasn't passing $onoff to the master's autoCommit()
    * Added DB_Virtual::queryMaster() so you can send queries directly to the master
    * Fixed a bug with last_query and getOne(), getAll(), etc.
    * Fixed a possible divide by zero error
    * Added check for weights less than zero
