It would be cool to have the possibility to combine multiple tiledb arrays in a single logical view.

A simple and fast way would be to require the same schema and just combine individual fragments s.t. the latest write wins.

A more useful option would be to also allow concatenation of arrays along some dimension.

In Dask, this could be exported as a single array with chunks aligned to the dataset borders.

Even better, one could include filtering options or joining by keys.
