RFC #2 - pt-online-schema-change

[thewillhuang]

nice tool! was wondering what are your thoughts on https://www.percona.com/doc/percona-toolkit/2.1/pt-online-schema-change.html and would that ever be a possiblity for node-db-migrate to utilize such a tool?

@thewillhuang This would need a binding or wrapper first, but I do have zero downtime on the feature list so it might be possible to use some external tool, or even implement those capabilities into the drivers itself. That depends, but this is quite interesting tool though.

Just have had another look at it and looked at the source and it seems to be quite decent. I will have some closer look of how compatible everything is to MariaDB and MySQL itself, or if many things are limited to percona. But that could make many things concerning zero downtime easier for the MySQL side.

Thanks for sharing :)
