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
Hi, Lekshmi ~
The FilterableTable can be scanned with a list of filter expression, that means
the filter conditions above the project + scan can be pushed directly into the
table scan[1][2], which is more efficient. Here is a CsvFilterableTable example
[3].

Hi,
Can anyone explain to me what is the advantage of Filterable Table? How
can we efficiently make use of that in a Federated system?
Thanks and Regards
