We are not longer alone implementing Google Dremel and BigQuery technology. A proposal was made recently to Apache Foundation suggesting similar project. Moreover Ted Dunning kindly invited us to take part in the project.
The project is just starting now and there is no source code yet and not even a consensus design. So we sat together today evening and wrote a proposed design for Apache Drill. We already working for about two years on Dremel and BigQuery implementation. It was a fascinating journey and we have learned quite a lot and would be more than happy to share our experiences and accumulated knowledge.
All our code (OpenDremel/Dazo/ZeroVM) has Apache License from the beginning and used several Apache technologies from Avro to Velocity. Apache seems to be best home for Drill project and we are looking forward to contribute to it.
