Coming back to this comment from Martin: how can we use temporary tables on Labs? They don't seem to be available on a connection to wiki replica DBs:
MariaDB [fawiki_p]> create temporary table tmp(i int); ERROR 1044 (42000): Access denied for user 's12345'@'%' to database 'fawiki_p'

Hmm, does create temporary table work? If not, can it?

I was thinking of running a query, temporarily store its output on ToolsDB. Join it with some other query and then throw it away. All in small scale and for short-term.

No, the wikireplicas are read-only.
That said, ToolsDB (Toolforge user DB) is not equipped to handle becoming an aggregate datamart for the wiki replicas at any thing close to large (wiki) scale--just small chunks that are ideally regularly cleaned up. Are we talking about a database on a Cloud VPS instance or ToolsDB?

Hi all, Is it possible to store data into user tables through queries on Wikireplica DBs? Or is it only possible by mysqldump'ing from the replica DB and loading into the user table in a separate step? I am thinking of aggregate data. Thanks!
