>
> Key: BEAM-59
> URL: https://issues.apache.org/jira/browse/BEAM-59
> Project: Beam
> Issue Type: New Feature
> Components: sdk-java-core, sdk-java-gcp
> Reporter: Daniel Halperin
> Assignee: Daniel Halperin
> Fix For: First stable release
>
>
> 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:
