Agree that this seems like a legitimate bug. The nullability going from false to true when the field exists on both schemas works as expected https://github.com/apache/arrow-rs/blob/2bc269c3eec23f6794fcd793b641ea4c08325d54/arrow-schema/src/schema.rs#L1330 In `try_merge` we simply iterate over all the schemas and merge each field: https://github.com/apache/arrow-rs/blob/2bc269c3eec23f6794fcd793b641ea4c08325d54/arrow-schema/src/schema.rs#L295-L319 Might there be existing use cases where this behavior is a feature and not a bug? -- This is an automated message from the Apache Git Service.
