--- Comment #13 from Sean Pringle <sprin...@wikimedia.org> --- FTR, correction for my comment #10: I said: "Note that I left term_language in terms_search despite the partitions because getMatchingIDs query still benefits from ICP when term_search_key is used with a poorly performing short prefix: LIKE 'a%'." This is actually wrong for MariaDB 5.5. ICP is not being used inside the partition (though it apparently will be possible in the future). Looks like the speed-up for getMatchingIDs here is only due to the pruning and the smaller partitioned indexes generating fewer Handler_read% hits. -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list Wikibugs-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
