Hello,

Is there a reader which takes in a list of columns or a avro/thrift
sub-schema and spits back a 2D array of rows?

If not can anyone please give me an idea on how to go about coding that up.
>From the "DumpCommand" example in  the parquet-tools code, i see that to
read multiple columns, it goes into a loop one by one and spits out one
column at a time. Is that the best way to do it?

Thanks,
