MySQL-MHA: HA replication tool

A new MySQL project about high availability is proposed by Yoshinori Matsunobu. This project permits to automating master failover and slave promotion within short downtime.

This is the first time that we can see a serious MySQL failover project into replication environment. I haven't tested it yet but lot of people speak about MySQL-MHA on the web actually. Yoshinori Matsunobu is associate with SkySQL for that they provide the commercial support.

MySQL-MHA brings a lot of advantages such as:

• Automated master monitoring and failover
• Interactive (manual) Master Failover
• Non-interactive master failover
• Online switching master to a different host

Every informations and descriptions can be found on the google code web page of MySQL-MHA.
You can know more about Yoshinori Matsunobu on his blog.

Project is released few days ago and I think that it will no need to wait for a long time to seeing this marvelous tools into your MySQL production replication environment.
