Ensure ids for newly created SFSB contexts will hash locally in Infinispan
--------------------------------------------------------------------------
Key: EJBTHREE-2050
URL: https://jira.jboss.org/jira/browse/EJBTHREE-2050
Project: EJB 3.0
Issue Type: Sub-task
Components: cache, Clustering
Reporter: Brian Stansberry
Assignee: Paul Ferraro
If Infinispan DIST is used, at least one of the cache locations for an SFSB should be the node that created it. This way in the normal case where there are 2 copies, a single unicast to the backup node is sufficient to replicate. If the cache key (the SFSBContext id) hashes to 2 remote nodes, then every cache write will require 2 unicasts.
The problem here is unlike web sessions, the id for an SFSB context is not generated by the caching layer; it's generated by StatefulBeanContext itself. So the web session strategy of having a background thread occasionally populate a pool of ids that are known to map locally (using the consistent hash algorithm Mircea Marcus is going to expose for ISPN-232) won't work.
