@HeartSaVioR Thank you for you Great Work . I have a small question about
`Mapper` extention structure .
> 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
> Assignee: 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.
