Emptying Civicrm_cache table
June 28, 2011, 11:53:40 am
I am moving some databases around, and my civicrm database is a decent size, but the majority of this is taken up by the civicrm_cache table (roughly 80%, or 40MB out of 50MB).

What is contained in the table? What would happen if I emptied it?

If you check the migration information it says to ignore that table and several others.

Cached data.

This should be safe to do at any time actually.

Is it a good idea to truncate civicrm_table table periodically?
Does it have any cons doing it?

It grows a lot and after 1 and half year using civicrm site a v3.4.8, that table size is 1.1Gb from 1.5Gb database

You are referring to the civicrm_cache table. It should remove old records by itself, but if yours is so big, then definitely truncate it yourself. It should not have any adverse effects as far as I know.
