 PyActiveStorage is designed to interact with various storage backends.

 We now have support for Active runs with netCDF4 files on S3, from [PR 89](https://github.com/NCAS-CMS/PyActiveStorage/pull/89).
 To achieve this we integrate with [Reductionist](https://github.com/stackhpc/reductionist-rs), an S3 Active Storage Server.
 Reductionist is typically deployed "near" to an S3-compatible object store and provides an API to perform numerical reductions on object data.

+To use Reductionist, use a `interface_type` of `s3`.
 
 To load metadata, netCDF files are opened using `s3fs`, with `h5netcdf` used to put the open file (which is nothing more than a memory view of the netCDF file) into an hdf5/netCDF-like object format.
 Chunk reductions are implemented in `activestorage.reductionist`, with each operation resulting in an API request to the Reductionist server.
