yup that i already know....
but is there any way to make it do the update more frequently.... 4 times in 30 mins... which makes the stats useless....
or there is any way to identify the usage of tables... wht i am trying to do is check the table heap_blks_read time to time.... so that i can know how much io is getting used for each table... and during which time... i am doing sampling every 2 min....
now after i have identified which tables are getting used and when... we can move them to diff partitions for better preformance.....
is there any way to know the table usage....
thx
