--- Comment #15 from Sean Pringle <sprin...@wikimedia.org> --- 16 partitions, a number chosen after some rough back-of-napkin style calculations for the larger wikis. The effect of accessing multiple partitions is closest to UNION. I don't anticipate excessive sorting or limiting penalties for our other queries though I do want to see how range access and index scans perform. Monitoring for queries adversely affected is definitely necessary and one of the reasons for only partitioning one slave per shard. -- 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
