I have updated the PR based on all the feedbacks here. Now you could see
that we now support CompoisteRowType and we are able to specify multiple column
families along with the qualifier names.
We are able to retrieve the result by doing a full scan.
This is not efficient and we need to specify start and end rows. I think
that can be done after FilterableTableSource is done.
I have added test cases that shows single column family and double column
family.
For now if the TypeInformation is not known we use plain byte[] type only.
That happens at the validation state itself. But one main concern from my side
is how to present the 'NULL' means we specify a column with a type but there is
no data for that column. For now I have handled by returning the Int, Float,
Long - Min_values. But that may not be right I believe. Feedback and
suggestions welcome.
