> Reported by a user in the field -
> We're generally getting read speeds of about 100-150 MB/s/node on PARQUET
> scan operator. This seems a little low given the number of drives on the node
> - 24. We're looking for options we can improve the performance of this
> operator as most of our queries are I/O bound.
