[rt-users] RT and mysql replication
Hi. I'd googled about this quesitons, but I'd find no useful information. You can simply tell me RTFM, but please link the FM I must R... ;-) Is there an RT support for mysql replication, a single master/many slave databases simple clustering method described in this page? http://dev.mysql.com/doc/refman/5.0/en/replication.html -- Luca VillaniMobile Team, Dada S.p.A.

Mysql supports replication, for sure at 4.x, and supports clusters at 5.x. Do the needful at the mysql level, RT doesn't care. Just make sure to use a version of mysql supported by RT. (We happen to use replication with 4.x, but there is nothing in RT that would depend on this.) bobg ___ http://lists.bestpractical.com/cgi-bin/mailman/listinfo/rt-users Community help: http://wiki.bestpractical.com Commercial support: [EMAIL PROTECTED] Discover RT's hidden secrets with RT Essentials from O'Reilly Media.

Hi, Just to pick up this discussion, this palnned scenario would be very, very clever, should be added to the rt4 wish list. Torsten. Btw: on on mysql cluster won't help if you have on on very big environment, the replica architecture would be the best way i think. -Original Message- From: [EMAIL PROTECTED] [EMAIL PROTECTED] To: rt-users@lists.bestpractical.com rt-users@lists.bestpractical.com Sent: Fri May 04 16:27:05 2007 Subject: Re: [rt-users] RT and mysql replication Alle 15:39, venerdì 4 maggio 2007, Bob Goldstein ha scritto: I don't believe this is an RT question.

Re: Re: [rt-users] RT and mysql replication
I know that this does not help your situation, but pgpool will allow you to perform select queries to a slave postgresql DB and updates to the master DB. There may be a similar proxy available for MySQL that would allow you to scale your DB load better.
