implementing a "grow_coordinate" function to grow / reallocate larger arrays copying the previous chunk along a coordinate

this sounds a lot like pad with mode="constant"?

is it possible that xarray makes no assumptions of this kind

xarray uses pandas indexes for alignment and indexing (if you have a recent version of xarray you should see the "Indexes" section in the HTML repr), so yes, it will always make sure to use a search that is more efficient than the linear search, as long as the data is sorted. This was also the reason why you had to use swap_dims / set_index to create an index along the coordinate you wanted to reindex.

I'm a bit surprised. Could you post a repr of timestamps_extended_basis? That might help figuring out what exactly happened.

If everything fails, you might also create a new xarray object with just the new values, and then use xr.concat to combine both?

I think this is because you don't have an index along the dimension. Try any of python previous_observations.set_coords(["timestamps"]).swap_dims({"time": "timestamps"}).reindex(...) previous_observations.set_index({"time": "timestamps"}).reindex(...) (the only difference is the name of the dimension / coordinate you end up with)
