Smart L1 cache invalidation --------------------------- Key: ISPN-186 URL: https://issues.jboss.org/browse/ISPN-186 Project: Infinispan Issue Type: Feature Request Components: Distributed Cache Reporter: Manik Surtani Assignee: Pete Muir Labels: l1 Fix For: 5.0.0.BETA1, 5.0.0.Final Need to build a mechanism in which L1 invalidation is NOT multicast, but instead is unicast _if necessary_ to specific nodes that may have cached a given entry. This can be detected by maintaining a list of nodes who have requested a key via a remote get, but this would need to be relayed by all data owners. Benefits would be performance by removing unnecessary invalidation where this is not needed, and by reducing noise in network stacks of most nodes.
