ANALYZE TABLE : How often ?
Posted by: Nick

Hi,

The MySQL documentation said :
"If the table has not changed since the last ANALYZE TABLE statement, the table is not analyzed again."

What does it mean "changed" ? Table changes with insert/update/delete ? with adding or removing indexes ? with altering schema ? all of this ?

Do I have to put an ANALYZE TABLE statement on all my tables in a cron, midnight, every days ? every month ? ...? :)

Thanks in advance for any advice,
Nick
