> Switch from IOChannelFactory to FileSystems
> -------------------------------------------
>
> 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:
> Design docs posted on dev@ list:
> Part 1: IOChannelFactory Redesign:
