Hi, I'm Vathsala Weerasinghe, a final year undergraduate of the Department of Computer Science and Engineering, University of Moratuwa, Sri Lanka.
Currently we are looking into the derby source to improve the hash join performance as a group project. We are trying to identify the implementation of the hash join in Derby. Now we are looking into HashJoinStrategy class in the org.apache.derby.impl.sql.compile package. Can someone guide us towards the correct path or provide us some good resources which will help us in tackling this problem? Thanks in advance. -- Regards, Vathsala Weerasinghe
