yo @Percona pretty much every sentence in your discussion of CAP is wrong https://www.percona.com/doc/percona-xtradb-cluster/5.6/intro.html#what-is-core-difference-percona-xtradb-cluster-from-mysql-replication …

@aphyr Yeah, it does seem incorrect. I have asked for that section to be removed. (seems to have derived from some really old docs)

@randomsurfer also would you mind adding a section describing the isolation levels Percona supports please? :) -
@aphyr Sure, I will ask the documentation team for it. But, it shouldn't much different from http://galeracluster.com/documentation-webpages/isolationlevels.html … -
@aphyr Other than the possibility for session-level dirty reads from non primary component(s) during partition. -
@randomsurfer whoah, wait, *dirty* reads? -
@aphyr https://www.percona.com/doc/percona-xtradb-cluster/5.6/wsrep-system-index.html#wsrep_dirty_reads … It also seems to be in MGC you tested: https://mariadb.com/kb/en/mariadb/galera-cluster-system-variables/#wsrep_dirty_reads … (though slightly different implementation) -
@randomsurfer Ah, it defaults to off though. :) -
@aphyr Yes, and for a good reason :) also it is a session-only variable (ie. not a global one) to avoid any anomalies. -
@aphyr It is meant to be more for debugging and maintenance on non-PRIM nodes. Discussed here https://github.com/codership/mysql-wsrep/issues/36 … initially.. - Show more
