---------------------------------------
Summary: Add S3A support for Async Scatter/Gather IO
Key: HADOOP-15964
URL: https://issues.apache.org/jira/browse/HADOOP-15964
Project: Hadoop Common
Issue Type: Sub-task
Components: fs/s3
Affects Versions: 3.3.0
Reporter: Steve Loughran
HADOOP-11867 is proposing adding a new scatter/gather IO API.
For an object store to take advantage of it, it should be doing things like
* coalescing reads even with a gap between them
* choosing an optimal ordering of requests
* submitting reads into the executor pool/using any async API provided by the
FS.
* detecting overlapping reads (and then what?)
* switching to HTTP 2 where supported
Do this for S3A
