Hi, I am doing a study about MapD Core system and I am interested to know some of its technic aspects. I have read “An Overview of MapD (Massively Parallel Database)”  and the “MapD Technical Whitepaper”  as well as some publications in the MapD blog but I still have some things I would like to clarify. Do you have any other technical documentation?
There is also a high level architectural diagram in the forum MapD data architecture map describes "what" comprises the data architec?
At this point you would need to go to the code in OS repo to get the next level of detall.
We are working on improving internal documentation to allow it to be exposed to the wider world, but no timeline on availability.
