Re: Transaction Commit and Rollback Support MyISAM

By "transactional table type" I mean either InnoDB or BDB (but the latter is only included in -max versions). There are also some non-MySQL AB storage engines in the wild that might do the trick. And possibly there might be even more in the future.

MyISAM does not support transactions and probably never will.

But we are working on a feature that can rollback commands that were active when the MySQL server crashed. It will also be possible to explicitly rollback everything from the point of a LOCK TABLES as long as no UNLOCK TABLES has been done so far.

Please do not think of it as transactional. The way MyISAM stores data does not guarantee you anything when the machine (or better the operating system) crashes. You won't be able to undo nor redo MyISAM tables to a clean state.
