TileDB Core

"Currently, if your array consists of more than one attributes, TileDB requires you to provide values for all the attributes in each write operation." I'd love to be able to write attributes independently of each other.

TileDB should support attaching axes labels (dataframes in their full generality), so that the user can slice the array based on arbitrary axes label predicates.

TileDB currently performs only slicing. It should allow other computations, such as filters, group-by queries and joins. This will help high-level application push compute closer to storage.

The user should be able to modify the array schema (e.g., add/remove attributes, change filters, tile capacity, etc) and time travel over the different versions.
