Re: [Maria-discuss] R: 'Converting' a myisam to multi-master
I think there is a misunderstanding here: XtraDB Cluster may have a confusing name, but it is not XtraDB, it is a cluster solution. The article explains it can work with MyISAM.

Re: [Maria-discuss] R: 'Converting' a myisam to multi-master
Hi Federico... wsrep_replicate_myisam=ON i will test galera very soon =) but today i'm using aria :/ maybe i will have problems?! 2013/9/19 Roberto Spadim robe...@spadim.com.br: sorry, i forgot one point important... MariaDB’s multi-source-replication doesn’t have any conflict resolution. The assumption is that there are no conflicts in data between the different masters. Which is the case here, all standalone servers handle different schemas. in this case i don't know if i will have conflict... that's why a multi master (sync) should be used and not a async replication 2013/9/19 Roberto Spadim robe...@spadim.com.br: Hi Federico! yes, but they don't recommend because the table lock level (not row level) and no transaction support in this case (app using myisam/aria today) it's not a problem the app works nice, but myisam/aria don't have a solution for multimaster yet :/ i used DRBD some time but it's a master-slave solution using xtradb cluster, is a problem since index, row size, no begin/commit at app, and xtradb don't have good min/max/count optimizations :/ i'm considering reading the galera cluster and maybe add some support to aria/myisam, but i didn't start anything yet, maybe there's a easier solution that i didn't know yet... 2013/9/19 Federico Razzoli federico_...@yahoo.it: The link explains how Percona replicated MyISAM tables in a multimaster environment using XtraDB Cluster + MariaDB.
