> Right now, FileBasedSource and FileBasedSink communication is mediated by IOChannelFactory.
There are a number of issues:
> * Global configuration -- e.g., all 'gs://' URIs use the same credentials. This should
be per-source/per-sink/etc.
> * Supported APIs -- currently IOChannelFactory is in the "non-public API" util package
and subject to change. We need users to be able to add new backends ('s3://', 'hdfs://', etc.)
directly, without fear that they will be broken.
> * Per-backend features: e.g., creating buckets in GCS/s3, setting expiration time, etc.
> Updates:
> Design docs posted on dev@ list:
