> Currently HBase implementation uses GenericObjectMapper to convert and store values in backend HBase storage. This converts everything into a string representation(ASCII/UTF-8 encoded byte array).
> While this is fine in most cases, it does not quite serve our use case for metrics. 
> So we need to decide how are we going to encode and decode metric values and store them in HBase.
