spenczar opened a new issue, #37476: URL: https://github.com/apache/arrow/issues/37476
### Describe the bug, including details regarding any error messages, version, and platform. If you define a dictionary type to use an unsigned integer for its index type, and explicitly pass it to pyarrow.array, it'll get ignored and you'll find yourself with a signed index instead. ```py import pyarrow as pa dictionary_type = pa.dictionary(pa.uint64(), pa.string()) print(pa.array(['x'], dictionary_type).type) # dictionary<values=string, indices=int64, ordered=0> ``` Similarly for `uint32`: ```py import pyarrow as pa dictionary_type = pa.dictionary(pa.uint32(), pa.string()) print(pa.array(['x'], dictionary_type).type) # dictionary<values=string, indices=int32, ordered=0> ``` ### Component(s) Python -- This is an automated message from the Apache Git Service.
