Actually that query is not my concern :i have a query that is taking so much time :Slow Log Output :# Overall: 195 total, 16 unique, 0.00 QPS, 0.31x concurrency _____________# Time range: 2012-09-01 14:30:01 to 2012-09-04 14:13:46# Attribute total min max avg 95% stddev median# ============ ======= ======= ======= ======= ======= ======= =======# Exec time 80887s 192us 2520s 415s 1732s 612s 80s# Lock time 13ms 0 133us 68us 103us 23us 69us# Rows sent 430.89k 0 17.58k 2.21k 12.50k 3.96k 49.17# Rows examine 32.30M 0 466.46k 169.63k 440.37k 186.02k 117.95k# Query size 65.45k 6 577 343.70 563.87 171.06 246.02In the logs output :# Query_time: 488.031783 Lock_time: 0.000041 Rows_sent: 50 Rows_examined: 471150SET timestamp=1346655789;SELECT t0.id, t0.app_name, t0.status, t0.run, t0.user_name, t0.group_name, t0.created_time, t0.start_time, t0.last_modified_time, t0.end_time, t0.external_id FROM WF_1 t0 WHERE t0.bean_type = 'Workflow' ORDER BY t0.created_time DESC LIMIT 0, 50;The table is near about 30 GB and growing day by day.Just out curiosity, is that table too fragmented? 471k rows are quite a lot, but 488 of query time is insane. Seems you're reading from disk too much!Attaching the table definition & indexes output. I have a index on bean type column but cann't understand why itexamined the all rows of table.Where's the table's schema so we can give it a try?Manu
