DOC: Configuration value 'array.v3_default_compressors' has been removed, but is still documented #3389
Description
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"tocreate_arrayshould get you an array with no compression at all.keller-mark commentedon Aug 19, 2025
Thank you for the quick response!
