The backend refactor has gone a long way towards making it easier to implement custom backend readers via entry points. However, it is still not clear how to implement a writeable backend from a third party package as an entry point. Some of the reasons for this are:

We should fix this situation! Here are the steps I would take.

  • [ ] Decide on the desired API for writeable backends.
  • [ ] Formalize this in the BackendEntrypoint base class.
  • [ ] Refactor the existing writeable backends (netcdf4-python, h5netcdf, scipy, Zarr) to use this API
  • [ ] Maybe deprecate to_zarr and to_netcdf (or at least refactor to make a shallow call to a generic method)
  • [ ] Encourage third party implementors to try it (e.g. TileDB)
