“Maria” ，－”a crash-safe alternative to MyISAM”，似乎有作为 InnoDB 继任者的可能。

Yet Another Engine

Apparently Monty and crew have been hard at work on yet another engine for MySQL, this one called “Maria” and is billed as, and I quote, “a crash-safe alternative to MyISAM” (hint, hint, for people still using MyISAM). Apparently it also will support a transactional mode as well, making it a possible successor to InnoDB, and perhaps a competitor to Falcon. It’s not clear how Falcon and Maria will interact in future versions of MySQL (I’d ask on Monty’s blog but it’s one of those unfriendly ones that won’t let the general public post to it).

I’ve still yet to be convinced that the multiple-engine theory is a good one, but it’s good to see that MySQL AB is recognizing the flaws of MyISAM and InnoDB (technical and legal, respectively) and making progress to replace them. Interesting times ahead.

Here’s a list of major features of Maria:

* ACID
* Commit/Rollback
* Concurrent selects (thanks to MVCC)
* Row locking
* Group commit
