Thanks, Albert ~
The ProjectableFilterableTable is indeed a little redundant, because we already
have ProjectableTable and FilterableTable, I think we can do some refactoring
to reduce such mixed in interfaces.
BTW, what do you mean by aggregate push down ? I can not figure out in which
case
talking about this class reminds me of my own usage of
ProjectableFilterable. it works.
but this feels like a very bad design, what if I want to push down
Aggregation ? AggregatableProjectableFilterable?
I don't know the intention of the initial design, but this just doesn't
feel right.

Hi Danny Chan,
Thank you so much for responding to my email. Can we use, Translatable
table instead of Filterable table? which is more efficient? Usecase that if
need to write a Project push down (Push down Project fields into table scan
then do Filtering) and Filter push down?
Or Filterable
There is a ProjectableFilterableTable[1] that can be both used for filter and
projects push down, have a try :)
