I just run spark-sql-perf (Q4, scalefacotr=4) on c4.4xlarge. I used the current master branch
and default configurations except for `spark.io.compression.codec`.

> ZStandard: https://github.com/facebook/zstd and http://facebook.github.io/zstd/ has been
in use for a while now. v1.0 was recently released. Hadoop (https://issues.apache.org/jira/browse/HADOOP-13578)
and others (https://issues.apache.org/jira/browse/KAFKA-4514) are adopting it.
> Zstd seems to give great results => Gzip level Compression with Lz4 level CPU.
