As a follow-up to a previous question I would like to know:
When should I use the category flat table option?
While googling I found an advice to enable it "when you have very much categories". But what is much?
I can easily understand, that activating flat tables for products is a good decision in terms of performance, but is it really as much important for catalogs?
And what implications conclude from this? I just learned that enabling flat category tables lead to not being able to save category product positions. At least not as easy as without the flat option (thx to Marius for your help). Are there any other mentionable things?
Thanks in advance :)
