Database structure changes

  • Removed units field from the xarray.chunks collection. Pint must always wrap around dask, and not the other way around.

  • DataArray.attrs was previously lost upon storage; it is now saved in the top-level attrs dict. (#10).

  • The attrs dict is now omitted if empty.

  • Added attrs dict under every element of coords and data_vars (omitted if empty).

  • Embed small variables into the metadata document. Added optional data key to each variable on the database. Added new parameter embed_threshold_bytes to control how aggressive embedding should be (see API Reference).

Packaging changes

  • xarray_mongodb now adopts a rolling Minimum dependency versions policy based on NEP-29.

    Increased minimum dependency versions:
