Description

Currently in calls to join the fillvalue must match the eltype of the arrays that are being joined. If an arbitrary fillvalue type were allowed and some kind of eltype promotion logic added one would have the option of using the much beloved missing as the fillvalue, which is maybe nice for workflows being ported from the various dataframes and/or Python's xarray.DaraArray.

Research direction

No file or test is named. Start by locating the join implementation and its existing fillvalue and eltype handling, then review current join tests. Done means join accepts an arbitrary fillvalue, including missing, with appropriate eltype promotion and passing coverage for the new behavior.
