Great tutorial, but why don´t you clarify, the best way to entry the database from an external consumer? 90% this can be an use situation.
Having MyISAM not replicated is usually a huge reward -- You could "Produce Short term Desk ... ENGINE=MyISAM" and also have it exist on just one node. RBR assures that any info transferred from that temp table into a 'authentic' desk can even now be replicated.

It also takes treatment of enough time taken to execute each statement. Furthermore, slave servers read this binary log from the grasp server in the event the replication of data is necessary. It, in general, would make MariaDB an outstanding facts replication program.
If the slave goes to connect with the master about the public World wide web, it is necessary to enable TLS encryption to circumvent targeted visitors snooping. Your server can have an online server with TLS enabled, so you can use that TLS certificate for MariaDB in addition.
