DOC: Configuration value 'array.v3_default_compressors' has been removed, but is still documented

[keller-mark]

Describe the issue linked to the documentation

Hi, I am trying to disable compression (at either the store level or array level or via zarr.config) in my script.

I tried

zarr.config.set({'array.v3_default_compressors': None})

which is documented at https://zarr.readthedocs.io/en/stable/user-guide/config.html

but it threw an error

ValueError: Configuration value 'array.v3_default_compressors' has been removed

It seems like this is still documented in several other places as well https://github.com/search?q=repo%3Azarr-developers%2Fzarr-python%20v3_default_compressors&type=code

Suggested fix for documentation

Beyond the array.v3_default_compressors configuration documentation, it would be helpful to provide an example in Working with arrays -> Compression which demonstrates how to disable compression options when using create_array

hi @keller-mark, sorry about the confusing state of affairs with the config + docs.

To answer your question, passing the kwargs filters=None, compressors=None, serializer="auto" to create_array should get you an array with no compression at all.

Thank you for the quick response!
