FineGrainedAtomicHashMap should support independent write skew checks for each key ---------------------------------------------------------------------------------- Key: ISPN-3123 URL: https://issues.jboss.org/browse/ISPN-3123 Project: Infinispan Issue Type: Enhancement Components: Core Affects Versions: 5.3.0.Beta2 Reporter: Dan Berindei FineGrainedAtomicHashMap supports fine-grained locking in pessimistic mode, but in optimistic mode the write-skew check is still done for the entire map. The write skew check should be done for each entry of the map individually, so that multiple transactions can update the same FineGrainedAtomicHashMap at the same time.
