[jbosscache-dev] Issue with FileCacheLoader with EJB3 SFSB Cache

The stress testing Philip Thurmond's been doing on ejb3 clustering has surfaced an issue with FileCacheLoader (see http://jira.jboss.com/jira/browse/EJBTHREE-937). Basically we're hitting file system limits on the number of directories. I can fix the issue by making a simple change to the structure of cached data. There would be a performance hit from that (probably not large). But, since we recommend not using FileCacheLoader anyway, I was planning to work on getting away from FileCacheLoader anyway for AS 5; this issue tempts me to do it now. What do people think about using JdbmCacheLoader instead of FileCacheLoader? It's been part of JBC for nearly a year now, and I'm not aware of any problems with it. Elias, I'd particularly like your opinion on this, as you obviously know the most about JdbmCacheLoader and probably know the most about JDBM. QE's doing intensive stress testing of 4.2, so if we switch JdbmCacheLoader will be put through its paces. -- Brian Stansberry Lead, AS Clustering JBoss, a division of Red Hat brian.stansberry(a)redhat.com
