> 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 ABFS
