Renato Javier Marroquín Mogrovejo commented on GORA-444:
--------------------------------------------------------

Hey guys,

So it is true that not all of the systems provide this in the same way, but there might be
ways on how to get this. For example Accumulo and HBase have a way to get/set the batchSize
of the elements fetch.  However, I don't think we have set this values, maybe we should set
them, and keep track of how many we are actually reading on the getProgress method.

> Right now we iterate through results by doing

> {code}
> It is a pain to always require a counter of sorts and would be much more intuitive to
provide a simple #size() method.
