[17:00:32] Reedy_: volans: I could really use some help trying to understand how the DB handles INDEXes. [17:00:34] EXPLAIN SELECT * FROM externallinks_global FORCE INDEX (APIINDEX1,APIINDEX2,APIINDEX3,APIINDEX4,APIINDEX5,APIINDEX6,APIINDEX7,APIINDEX8) LEFT JOIN externallinks_paywall ON externallinks_global.paywall_id=externallinks_paywall.paywall_id WHERE ( `live_state` IN (0, 7) OR externallinks_global.paywall_id IN (SELECT paywall_id FROM externallinks_paywall WHERE `paywall_status` IN (3)) ) AND `reviewed` = 0 LIMIT 10000 [17:00:34] 0,1001; [17:00:49] But none of those indexes actually take in the query. [17:01:51] After working long and hard, I think this general query will optimize performance and get what I need, provided the indexes I setup are used. What am I doing wrong? I feel rather useless/helpless now. [17:22:51] legoktm: I need a sysadmin. [17:23:02] I would like to rename an account with 75k edits.
