> 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.
