Performance

Ruby Apps Ferret

Hi

AS you know ferret does indexing on the methods also. This feature can
be used to
do full text search on columns + tags(implemented using
acts_as_taggable).

I have a db where there are three tables say A,B,C

The relationships are like - A has many B and B has many C. My tags go
against table C. But I have to do full text search on columns of A +
tags on C.

What I can do is have an instance method for A which finds all grand
child of A in C and returns their tags as a string which can be indexed.
But wont that effect the performance a lot?

Any suggestion

Well, you can’t tell without trying this out :wink:

If it turns out to be a bottle neck, I’d rethink about optimizing this.
