Description

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.
