> Implement an S3 filesystem for Python SDK

> Issue Type: Task
> Components: sdk-py-core
> Reporter: Dmitry Demeshchuk

> There are two paths worth exploring, to my understanding:
> 1. Sticking to the HDFS-based approach (like it's done in Java).
> 2. Using boto/boto3 for accessing S3 through its common API endpoints.
> I personally prefer the second approach, for a few reasons:
> 1. In real life, HDFS and S3 have different consistency guarantees, therefore
> their behaviors may contradict each other in some edge cases (say, we write
> something to S3, but it's not immediately accessible for reading from another
> end).
> 2. There are other AWS-based sources and sinks we may want to create in the
> future: DynamoDB, Kinesis, SQS, etc.
> 3. boto3 already provides somewhat good logic for basic things like
> reattempting.
> Whatever path we choose, there's another problem related to this: we
> currently cannot pass any global settings (say, pipeline options, or just an
> arbitrary kwarg) to a filesystem. Because of that, we'd have to setup the
> runner nodes to have AWS keys set up in the environment, which is not trivial
> to achieve and doesn't look too clean either (I'd rather see one single place
> for configuring the runner options).
> Also, it's worth mentioning that I already have a janky S3 filesystem
> implementation that only supports DirectRunner at the moment (because of the
> previous paragraph). I'm perfectly fine finishing it myself, with some
> guidance from the maintainers.
> Where should I move on from here, and whose input should I be looking for?
> Thanks!
