Thanks guys for the interest. I'm really excited about all the feedbacks from the community.
A little background: we developed Scio to bring Google Cloud Dataflow closer to the Scalding/Spark ecosystem that our developers are familiar with while bringing some missing pieces to the table (type safe BigQuery, HDFS, REPL to name a few). I have to admit that I'm pretty new to the BEAM development but would love to get feedbacks and advices on how to bring Scio closer to BEAM feature set and semantics. Scio doesn't have to live with the BEAM code base just yet (we're still under heavy development) but I'd like to see it as a de facto Scala API endorsed by the BEAM community. @Ismaël: I'm curious what's this session thing you're referring to?
