Does MariaDB have any plans to support explain for insert/update/delete/replace/CTAS? There have been feature requests open for a very long time on official MySQL without any progress. I have had a few problems in production from 'bad' delete statements that had a very different plan than the select statement with the same where clause. The only way to check for a bad plan today is to use SHOW INNODB STATUS to determine whether the statement locks all rows in a table.

AFAIK at this point a definitive list of possible features to implement in MariaDB has not been created. That may well be a topic at the company meeting in 3 weeks. It is my assumption that we will be looking through historical feature requests and making some attempt to prioritize them by largest affected userbase. IOW, I would personally like to implement those features that will satisfy the largest cross-section of users. That having been said, feature requests and such non-recurring engineering is a keystone of the Monty Program business model. You can guess where I'm going from here ... ;) -- ./k kurt von finck http://www.mneptok.com public key: keyserver.ubuntu.com key id: 5229D26A fingerprint: 127A A484 ADBF A5AD E7FB 8CD2 8913 18F4 5229 D26A Music is the space between the notes. - Debussy
