Query in Toolforge couldn't complete (timeout)
Closed, DuplicatePublic


Hello, since Mar 9 2019 "Update for the actor table change" the server took too long for any quarry, for example this quarry takes 312.47 second in quarry.wmflabs, but in Toolforge it couldn't even complete, I get "2013 Lost connection to MySQL server during query" or timeout.

Using optimizer:

  • You appear to be querying the revision table and filtering by user. It may be more efficient to use the revision_userindex table.

@matej_suchanek same problem when I use the revision_userindex table.
