Subject RE: select * causing " OutOfMemoryError: Java heap space"
Date Thu, 13 Mar 2008 14:24:33 GMT
What is you JVM heap size set to and how much data is returned by select * from table?

If you're trying to pull back 1G worth of data into a JVM with a heap size set to 64M, you
will hit the heap limit pretty quick.

Subject: select * causing " OutOfMemoryError: Java heap space"

Hi, everybody.
I'm testing the Compass search engine and, in particular, how to index a big set of documents
from a table in a MySQL database. In order to do this I issue a "select * from table_name"
using iBatis, but this seems to be causing the application to use all heap space available.
I added a new entry into Compass user forum with details:

Can you figure out why is this happening?

Many thanks
