-----------------------------------------
I am getting errors in the tests running against s3 express storage and the
2.33.8 SDK.
[~ahmar] you tested this against s3 express storage and all is good, right?
> S3A Analytics Accelerator: vector IO support
> --------------------------------------------
>
> Key: HADOOP-19394
> URL: https://issues.apache.org/jira/browse/HADOOP-19394
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.1
> Reporter: Steve Loughran
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.5.0, 3.4.3
>
>
> Add vector IO support for analytics accelerator stream
> Three stages
> # pull up s3a input stream to work with all ObjectInputStreams; do its own
> fetching independent of the analytics stream
> # provide info to stream of fetches having taken place (remove from cache,
> cancel prefetch)
> full integration
> * return a range from cache if present
> * append to the block retrieval callback if a prefetch is in progress
> * only do merge + new request if the range cannot be satisifed entirely from
> cached data
> Out of scope: handling case where part of a range is in cache/retrieval. Too
> complicated and so prone to problems.
