Re: Google Summer of Code 2019 for Apache Arrow

I agree with Antoine. The more well-defined and less uncertain the project, the higher the probability of success. I had suggested implementing a bridge between one or more database protocols (e.g. SQLite3 or libpq / PostgreSQL) as example projects that could get done in 3 months. By the way, if

Arrow on WebAssembly

Re: Arrow on WebAssembly

Hi Franco, I'm not aware of anyone trying this in Rust, but Tim Paine at JPMC recently contributed a patch [1] to make it possible to compile the C++ implementation with emscripten, so that he could use it in Perspective [2]. Could you use the C++ lib instead? It would be great if either
