Wes McKinney commented on PARQUET-600:
--------------------------------------
We may look at the RLE encoding/decoding implementations (in C) in HAWQ (for

https://github.com/apache/incubator-hawq/blob/master/src/backend/cdb/cdbparquetrleencoder.c
In general adding vector encoding / decoding might be a good first step.
> Add benchmarks for RLE-Level encoding
