paleolimbot opened a new issue, #49674: URL: https://github.com/apache/arrow/issues/49674
### Describe the bug, including details regarding any error messages, version, and platform. Found when working on dictionary encoding in nanoarrow in https://github.com/apache/arrow-nanoarrow/pull/861 ...I have yet to confirm independently of that. The bit of code this affects for me checking a roundtrip of an empty record batch through IPC...I am not sure it actually makes sense for any practical purpose to have an empty (but ordered) dictionary. ```c EXPECT_EQ(maybe_batch.ValueUnsafe()->ToString(), empty->ToString()); if (data_type->id() != arrow::Type::DICTIONARY || !std::static_pointer_cast<arrow::DictionaryType>(data_type)->ordered()) { EXPECT_TRUE(maybe_batch.ValueUnsafe()->Equals(*empty)) << empty->ToString(); } ``` ### Component(s) C++ -- This is an automated message from the Apache Git Service.
