[PHP-DB] optimizing indexes -mysql

2006-05-04 Thread blackwater dev

I just doubled the size of my MySQL db, is there a command I should run to
re-index everything or is that automatic?

Thanks!

Well, it is automatic and MySQL does not need a lot of attention.
Having said that, what table type(s) are you using, and what version of 
MySQL? And in the process of doubling were there  a lot of deletions?


If you have a lot of DELETEs in a MyISAM table, for instance, that space is 
maintained as a linked list until it can be re-used. Running OPTIMIZE TABLE 
against that will reclaim the space.


This is really a question that should be asked on a list dedicated to MySQL.
