Re: full text search

Can you run EXPLAIN on one of the queries and examine the query plan? If the query uses temporary tables and the result is too big then mysql will spill the temporary tables to disk and that can cause a significant slowdown.

Some good references on EXPLAIN:

Hi all,

thanks to ur quick reply,

i m using nested queries to join to two table and  in googel cloud sql, we stored 100k of records and now while searching through google app its taking too much time and page not display anything.

and in log its showing following error,

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.

Hi , 

I imported a DB (~100k rows) on which I am doing full text searches, 
In CloudSQL they are taking more than 30 seconds causing 
Apennine to exceed the request time limit. 

Any suggestions? Or are full text searches just too slow to be done in 
the GCS?
