[asterisk-ha-clustering] Wanted: High-Available and reliable MySQL Back-end for Asterisk

[Oli Sennhauser]

Hello all,

We have seen up to know that MySQL was used in a Master-Master 
Replication Set-up for HA Asterisk back-ends. Master-Master Replication 
has limited scalability and causes some troubles with fail-over and data 
inconsistencies.

Now we want to test how Asterisk behaves with MySQL synchronous 
multi-Master Replication and Galera (http://codership.com/).

Added benefits with Galera replication is that Asterisk servers can 
write to any MySQL Server in the Cluster and:

* does Synchronous Replication
* uses InnoDB tables
* is an active-active real multi-Master topology
* does automatic membership control
* is true parallel Replication on row level
* has no Slave lag
* does not loose transactions
* scales reading and writing

Galera Cluster can be used in a LAN or a WAN!

We are a database company and have no clue about Asterisk and VoIP. Thus 
we are looking for somebody who wants to test this set-up together with us.

Please let me know when you are interested so we can figure out the 
details. Thanks for volunteering!

Best regards,
Oli
