> S3A: Cut S3 Select
> ------------------
>
> Key: HADOOP-18830
> URL: https://issues.apache.org/jira/browse/HADOOP-18830
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
>
> getting s3 select to work with the v2 sdk is tricky, we need to add extra
> libraries to the classpath beyond just bundle.jar. we can do this but
> * AFAIK nobody has ever done CSV predicate pushdown, as it breaks split logic
> completely
> * CSV is a bad format
> * one-line JSON more structured but also way less efficient
> ORC/Parquet benefit from vectored IO and work spanning the cluster.
> accordingly, I'm wondering what to do about s3 select
> # cut?
> # downgrade to optional and document the extra classes on the classpath
> Option #2 is straightforward and effectively the default. we can also declare
> the feature deprecated.
