> S3A: InputStreams to be created by factory under S3AStore
> ---------------------------------------------------------
>
> Key: HADOOP-19354
> URL: https://issues.apache.org/jira/browse/HADOOP-19354
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.2
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Labels: pull-request-available
> Fix For: 3.5.0
>
>
> Migrate S3AInputStream creation into a factory pattern, push down into
> S3AStore.
> Proposed factories
> * default: whatever this release has as default
> * classic: current S3AInputStream
> * prefetch: prefetching
> * analytics: new analytics stream
> * other: reads a classname from another prop, instantiates.
> Also proposed
> * stream to implement some stream capability to declare what they are
> (classic, prefetch, analytics, other).
> h2. Implementation
> All callbacks used by the stream also to call directly onto S3AStore.
> S3AFileSystem must not be invoked at all (if it is needed: PR is still not
> ready).
> Some interface from Instrumentation will be passed to factory; this shall
> include a way to create new per-stream
> The factory shall implement org.apache.hadoop.service.Service; S3AStore shall
> do same and become a subclass of CompositeService. It shall attach the
> factory as a child, so they can follow the same lifecycle. We shall do the
> same for anything else that gets pushed down.
> Everything related to stream creation must go from s3afs; and creation of the
> factory itself. This must be done in S3AStore.initialize().
> As usual, this will complicate mocking. But the streams themselves should not
> require changes, at least significant ones.
> Testing.
> * The huge file tests should be tuned so each of the different ones uses a
> different stream, always.
> * use a -Dstream="factory name" to choose factory, rather than the -Dprefetch
> * if not set, whatever is in auth-keys gets picked up.
