[ https://issues.jboss.org/browse/JGRP-1825?page=com.atlassian.jira.plugin.... ] Manuel Dominguez Sarmiento commented on JGRP-1825: -------------------------------------------------- Hi Bela, we would appreciate a native ReadWriteLock implementation in JGroups. We are working on improving the EhCache-JGroups replication integration so that cluster consistency can be achieved with replicated read-write caches. ReadWriteLocks are a necessity for many scenarios and corner cases. The alternative seems to be using the current exclusive lock construct, with two different locks (one for reads, another for writes) together with a distributed COUNTER, but this is far from being efficient (too chatty). Perhaps something along the lines of the algorithms described in https://en.wikipedia.org/wiki/Readers–writers_problem -- This message was sent by Atlassian JIRA (v6.4.11#64026)
