Jinfeng Ni commented on DRILL-4800:
-----------------------------------
In the configuration parameter doc
https://github.com/parthchandra/drill/wiki/Drill-Parquet-Scan-Configuration,
the default value of `store.parquet.reader.columnreader.async` would be false,
right?
> Improve parquet reader performance

> 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.
