Re: Very slow "creating sort index"

An ANALYZE did solve the problem, for some reason some of the partitions seem to have had outdated index statistics, causing mysql not to use the index at all but apparently sort the whole table, before applying the where-condition (which results in 0 returned rows). Honestly, I cannot imagine a scenario, where this approach would make any sense.
