--------------------------------------
Assignee: Antoine Pitrou
> [Docs] Clarify immutability assumption in the C Data Interface documentation
> ----------------------------------------------------------------------------
>
> Key: ARROW-17924
> URL: https://issues.apache.org/jira/browse/ARROW-17924
> Project: Apache Arrow
> Issue Type: Task
> Components: Documentation, Format
> Reporter: Joris Van den Bossche
> Assignee: Antoine Pitrou
> Priority: Major
>
> The current documentation
> (https://arrow.apache.org/docs/dev/format/CDataInterface.html) is not
> explicit about whether there are any guarantees about (im)mutability.
> My assumption is that the _consumer_ of C Data Interface structs should
> _assume_ the data to be immutable by default (unless they would know that the
> producer is fine with mutating the data). But it would be good to document
> this.
> (as a reference, the DLPack Python docs mention this:
> https://dmlc.github.io/dlpack/latest/python_spec.html#semantics)
