Over the weekend I added preliminary Parquet support to DataFusion (it only supports int/float primitives and UTF8 so far). This was possible due to the great work happening with the parquet-rs crate.
Integrating this with the current Rust version of Arrow was simple and I have now started running benchmarks (and we now have some benchmark code checked into the Arrow project). Now that the basic functionality is stable enough to support this use case I am going to focus on quality this week and start improving unit tests and adding documentation. I think we might be at the point where it makes sense to start discussing a first official release and maybe a roadmap for the Rust library? My next area of interest personally is the IPC mechanism and interop testing with other languages, especially Java. Thanks, Andy.
