clintropolis commented on issue #6016: Druid 'Shapeshifting' Columns
URL: https://github.com/apache/incubator-druid/pull/6016#issuecomment-565357780
 
 
   I haven't forgotten about this branch, it has been in the back of my mind for a long time now (..like a really long time at this point heh). This PR is a really promising proof of concept, but it's still sort of rough around the edges and I think I can do even better. During this time, I've been thinking of some ideas on how this can better play into the vectorized query engine as well as how to always beat the segment sizes of the current approach. Of course I also still need to resolve the c++/java compatibility issue, because the c++ performance is too good to ignore (and also what LZ4 is doing so not without precedent in Druid) but we need a compatible java implementation in the event the native module is not able to load.
   
   My main blocker is that I have just been waiting until I have a contiguous chunk of time to resolve these issues, which with any luck I anticipate will be in a couple of weeks over the holidays 🎄
