Category: JBossCMP Group: CVS HEAD Status: Open Resolution: None Priority: 5 Submitted By: Michael Newcomb (mnewcomb) Assigned to: Nobody/Anonymous (nobody) Summary: read-ahead issues Initial Comment: I'm submitting this to keep track of some issues that have arisen with the rewrite of the read-ahead code. Most of the problems I am encountering have to deal with very large sets of data (to the tune of 10k+ entity beans). I'm just gonna give a quick summary of the problems, but if you are interested in the details, I can forward the e-mail thread between Dain and myself discussing the problems. Summary: 1. Replacing FinderResults with a List indirectly causes a large amount of compares to occur when working with 'listMap' because FinderResults.equals was just doing identity comparison as opposed to List.equals which starts walking the list comparing values. 2. Relationship read-aheads and finder read-aheads share the same 'listMap'. So, if a bean is found in a read-ahead and then in a relationship, the results keep getting replaced with the last accessed one.
