Description
With zarr-developers/zarr-specs#153, the V3 spec was updated to use a single codec field in array metadata, rather than the separate filters and compressor fields. The specific text is
codecs
Specifies a list of codecs to be used for encoding and decoding chunks. The value must be an array of objects, each object containing a member withtypewhose value is a URI that identifies a codec and dereferences to a human-readable representation of the codec specification. The codec object may also contain aconfigurationobject which consists of the parameter names and values as defined by the corresponding codec specification. An absent codecs member is equivalent to specifying an empty list of codecs.
AFAICT, this library (zarr-python) has not been updated to reflect this new concept. I'm opening this issue to keep track of this.
