@steveloughran - addressed latest comments.
I'll move AAL logs to debug before the AAL next release.
Do you know why yetus is complaing:
"https://github.com/apache/hadoop/pull/7334 does not apply to trunk. Rebase
required? Wrong Branch? See.. " wondering if this is because this branch was
originally based on top of your input stream branch
> S3A: Add initial support for analytics-accelerator-s3

> Reporter: Ahmar Suhail
> Priority: Major
> Labels: pull-request-available

> S3 recently released [Analytics Accelerator Library for Amazon
> S3|https://github.com/awslabs/analytics-accelerator-s3] as an Alpha release,
> which is an input stream, with an initial goal of improving performance for
> Apache Spark workloads on Parquet datasets.
> For example, it implements optimisations such as footer prefetching, and so
> avoids the multiple GETS S3AInputStream currently makes for the footer bytes
> and PageIndex structures.
> The library also tracks columns currently being read by a query using the
> parquet metadata, and then prefetches these bytes when parquet files with the
> same schema are opened.
> This ticket tracks the work required for the basic initial integration. There
> is still more work to be done, such as VectoredIO support etc, which we will
> identify and follow up with.
