Manik Surtani commented on JBCACHE-1494:
----------------------------------------
This is now a configuration option <locking .... useLockStriping="false"
/> will disable lock striping. Note that lock striping is enabled by default though.
Also, with lock striping disabled, concurrencyLevel is meaningless and ignored.
As would be expected, this is also on the Configuration class.
Lock-per-Fqn option in addition to lock striping, for MVCC

Key: JBCACHE-1494
URL:
https://jira.jboss.org/jira/browse/JBCACHE-1494
Project: JBoss Cache
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: Locking
Affects Versions: 3.0.3.GA
Reporter: Manik Surtani
Assignee: Manik Surtani
Fix For: 3.1.0.GA
Lock striping, while performant and memory efficient, can lead to deadlocks in certain
cases where several fqns map to the same lock. An alternative where a lock er fqn is used
may be desirable.
