Bug Description

[In:Percona XtraDB Cluster Documentation]

Please add a note to the my.cnf configuration options to mention that query_cache parameters need to be disabled - this caught me out several times:

# Query Cache is not supported with wsrep

Thanks for reporting. The documentation indeed needs to be updated, especially, since now it is possible to enable query cache at runtime for galera.


To quote from

 "To enable query cache, mysqld should be started with query_cache_type=1 and query_cache_size=0 and then query_cache_size should be changed to desired value during runtime."

Also, limitations page needs to be updated.

The 5.6.15-25.3 and 25.4 already support query cache as in #1, so 5.6 documentation needs to be updated.
