Support cloning a slave from an online master

[nevermort]

Hi guys. Thx for u'r great soft. Tell me pls, is there a solution in jetpants for adding (not clone) slave for single master (without any other slaves). (maybe, by using Percona XtraBackup or some other "hot" backup utilities)? I didn't find any stuff like this in jetpants.

Jetpants doesn't have support for hot-copy yet, but it is high on the priority list. Most likely it will wrap xtrabackup for this purpose.

Currently though all cloning is cold-copy, meaning the source mysqld is shut down and a physical file copy is performed. This is why the CLI's jetpants clone_slave command currently only allows cloning standby replicas. You can clone a master or read replica via jetpants console by running Ruby code, but this is a disruptive process since the source instance needs to be shut down.

Thanks for answer. We will expect from you even more excellent solutions and approaches (especially about hot backup process). My best regards!
