Support any combination of numcodecs codecs in v2 > v3 conversion CLI

Open K-Meech opened this issue 3 months ago • 0 comments

Currently, the CLI for converting v2 to v3 metadata (https://github.com/zarr-developers/zarr-python/pull/3257) only handles filters that are ArrayArrayCodecs and compressors that are BytesBytesCodecs (see discussion in thread). v2 metadata supported filters / compressors that were numcodecs codecs of any kind. This likely means that some v2 metadata will fail conversion to v3, and throw an error.

If possible, it would be useful to support any combination of numcodecs codecs.
