[Linux-HA] MySQL replication agent

2010-05-12 Thread Yves Trudeau
Hi, for the ones interested in building an HA solution for MySQL based on replication, I just updated a page on the wiki started by Florian whose goal is to create what would be in my mind the first real HA solution for MySQL based on replication. It is a discussion page so inputs are welcome.
