Google proposes its Dataflow batch/stream tech to the Apache Incubator
Seems like this would duplicate a rather large chunk of Apache Crunch, which implements Google Flume nearly exactly as far as public API is concerned. As far as I can tell, Google Dataflow is also a variation on top of Google Flume. It would be helpful if they could elucidate why this project would not be redundant under the Apache umbrella.
