URL: https://issues.jboss.org/browse/ISPN-1665
Project: Infinispan
Issue Type: Feature Request
Affects Versions: 5.0.0.FINAL
Reporter: Ondrej Nevelik
Assignee: Vladimir Blagojevic
Fix For: 5.2.0.ALPHA2, 5.2.0.FINAL
Add functionality to optionally use a combiner between Map and Reduce phases (see
http://research.google.com/archive/mapreduce.html part 4.3 Combiner Function). This
enables to adjust API to be less restrictive - Reduce.reduce function could consume and
return different types of objects.
