> S3 Select enables applications to retrieve only a subset of data from an object by using
simple SQL expressions.
> S3A connector for Hadoop adds an API that aims at supporting S3 select queries. This
issue initiates the work needed on the Hive side to create the S3 queries from the projection
and filter expressions pushed to TS operators.
