I am hoping that the 0.4 release of Julia will coincide with a major cleanup of the Data* world. I wrote up a very high level overview of my goals here: https://gist.github.com/johnmyleswhite/ad5305ecaa9de01e317e
There’s still more work to do to flesh out these ideas, but the basic principles are pretty close to finalized. There’s also a rough draft of much of the core functionality we’ll need to add to support this roadmap. I wanted to give everyone a heads up so that people understand where the Data* packages are headed. The big idea is that we’ll be pushing more work out into the type system, which will give substantial performance improvements. — John
