-----------------------------------

             Summary: Distributed streams should only send subset of keys when using filterKeys
                 Key: ISPN-6270
                 URL: https://issues.jboss.org/browse/ISPN-6270
             Project: Infinispan
          Issue Type: Enhancement
          Components: Distributed Execution and Map/Reduce
    Affects Versions: 8.1.2.Final
            Reporter: William Burns


Currently distributed streams sends all keys provided in filterKeys to each node.  We could improve this in 2 ways.

# Only send requests to nodes that have segments that map to desired keys
## We would also have to cross check this if user supplied specific segments
# Only send the keys that map to the nodes that have those segments instead of all

This should reduce possible # of messages and for sure reduce message payloads.
