[jira] [Created] (STORM-1919) Introduce FilterBolt on storm-redis

Jungtaek Lim created STORM-1919:
-----------------------------------

             Summary: Introduce FilterBolt on storm-redis
                 Key: STORM-1919
                 URL: https://issues.apache.org/jira/browse/STORM-1919
             Project: Apache Storm
          Issue Type: New Feature
          Components: storm-redis
            Reporter: Jungtaek Lim


While discussing about STORM-1880, it would be better to have FilterBolt explicitly instead of letting users set up their lookup mapper to act as filter.

There's other benefit here: we can use exists / hexists on STRING / HASH datatype instead of retrieving actual value which reduces execution time / latency from Redis side.
