This is due to a limitation in arrow-rs that does not support timestamps with timezones: every timestamp that enters arrow-rs and is transformed is outputted as a timestamp without timezone. Because `Timestamp(a,Some(b)) != Timestamp(a,None)`, the `RecordBatch` refuses to accept the transformed columns (as it expects one with timestamp). A solution in `DataFusion` is to apply an extra cast after every operator from arrow to the expected schema, thereby converting the array back to the expected logical type (until the next operator hits). This implies not using operators that return `RecordBatch` such as `batch_filter`, etc. (since afaik they also error in `arrow-rs`). -- This is an automated message from the Apache Git Service.
