raulcd opened a new pull request, #44701: URL: https://github.com/apache/arrow/pull/44701
### Rationale for this change Currently `from_buffers` is not working with StringView on Python because we validate against num_buffers. This only take into account the mandatory buffers but does not take into account the variadic_spec that can be present for both string_view and binary_view ### What changes are included in this PR? Take into account whether the type contains a variadic_spec for the non-mandatory buffers and only check lower_bound number of buffers. ### Are these changes tested? Yes, I've added a couple of tests. ### Are there any user-facing changes? We are exposing a new method on the Python DataType. `is_variadic` which tells us whether the number of buffers expected is only lower-bounded by num_buffers. -- This is an automated message from the Apache Git Service.
