@b-slim this is more of a working heads up (i.e. I think you can probably build your roaring bitmaps faster) rather than something I would expect you to merge. The fact that run compression can be applied incrementally so you don't need to do it when you serialise the bitmaps ripples out fairly quickly to "BitmapSerdeFactory" JSON formats, and I can't offer a view on how they should be kept backward compatible. If you upgrade, please feel free to use this commit as a reference.
