Object types in dataset #103
Description
When I try to write to zarr, I get the warning:
SerializationWarning: variable None has data in the form of a dask array with dtype=object, which means it is being loaded into memory to determine a data type that can be safely stored on disk. To avoid this, coerce this variable to a fixed-size dtype with astype() before saving it.
I guess this is coming from baseline_antenna column and field name. Would this be a performance issue?
