Sounds great, thanks. A number of people are looking at using Arrow for faster serialization for PySpark, so now that the Java and C++ libraries are compatible (cf: integration tests) we can make this a reality. On Thu, Dec 15, 2016 at 4:54 PM, Julien Le Dem wrote: > I'm happy to reach out to Ma

I think someone should reach out to Matei and Shoumik, and see if they would like to collaborate. Wes, would you like to do that? Also, reach out to the Spark community. Are they aware of Arrow? Are they planning to use it, or are they developing an alternative? Julian > On Dec 13, 2016, at

Re: CLang, LLVM and optimization during conversion

2016-12-15 Thread Wes McKinney
We've been developing and testing the Arrow C++ library with Clang, but haven't done any work on LLVM or code generation with it. It would be interesting to make it easy to create custom UDFs in LLVM and evaluate them on Arrow data -- a bit of glue necessary to bridge the Arrow world and the LLVM w
