Steve Loughran commented on HADOOP-18028:
-----------------------------------------
this is now merged into trunk. as such, i think we could close this as done,
and add another "stabilize" where the big ones to deal with are, IMO,
memory/disk use
> High performance S3A input stream with prefetching & caching

> I work for Pinterest. I developed a technique for vastly improving read
> throughput when reading from the S3 file system. It not only helps the
> sequential read case (like reading a SequenceFile) but also significantly
> improves read throughput of a random access case (like reading Parquet). This
> technique has been very useful in significantly improving efficiency of the
> data processing jobs at Pinterest.
>
> I would like to contribute that feature to Apache Hadoop. More details on
> this technique are available in this blog I wrote recently:
