Hi There, It seems a stupid question but only to have a confirmation. How is safe using Myisam engine in CtraDB cluster. I know that mysiam engine is not fully tested. Can someone give me more details and wich are the issues about using Mysaim engine ? Thanks. Stofa. ---

Do not use it. We had once a wordpress blog which installed its table as myisam and the pxc did crash upon usage. [url][https://www.percona.com/doc/percona-xtradb-cluster/5.7/limitation.html[/url]](https://www.percona.com/doc/percona-xtradb-cluster/5.7/limitation.html%5B/url%5D) states “experimental” Check if it is possible to move to InnoDB with these tables.

Right. Avoid using MyISAM with PXC as MyISAM is non-transactional and so transaction using MyISAM can’t be rolled back.
