Hi @tlogan2000 , this is moving forward but slowly.

The good news is that I got resampling working this week (at least for some minimal test cases). It works by rechunking so that every chunk boundary lines up with a group boundary, and then applies numpy_groupies blockwise.

https://github.com/dcherian/dask_groupby/blob/8a30c4b20f23acacfc3b53dbeab2a7b268ecd3fc/dask_groupby/xarray.py#L268-L272

You can test it out with something like this python dask_groupby.xarray.resample_reduce(ds.resample(time="M"), func="mean")

For general groupby use python dask_groupby.xarray.xarray_reduce(...) This still fails a few xarray tests but a lot of them pass! Let me know how it goes and please file bug reports over at the dask_groupby repo if you find any.
