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

             Summary: Change the RocksDB implementation for KStream windowed 
aggregations, to not use “range queries” but multiple gets
                 Key: KAFKA-3778
                 URL: https://issues.apache.org/jira/browse/KAFKA-3778
             Project: Kafka
          Issue Type: Sub-task
          Components: streams
    Affects Versions: 0.10.1.0
            Reporter: Eno Thereska
             Fix For: 0.10.1.0


RocksDbWindowStore currently does not use caches (while RocksDbStore does). 
Enable caching for RocksDbWindowStore. This might require changing the API from 
using range queries to using multiple gets(), one for each sub-range.
