### Is your feature request related to a problem or challenge? We currently support reading Arrow files: https://github.com/apache/arrow-datafusion/blob/95ba48bd2291dd5c303bdaf88cbb55c79d395930/datafusion/sqllogictest/test_files/arrow_files.slt#L1 However, we do not support writing them: ``` ❯ copy (values (1)) to '/tmp/data.arrow'; This feature is not implemented: Writer not implemented for this format ``` ### Describe the solution you'd like I would like to be able to write to arrow files using the `COPY` command and `EXTERNAL TABLE`s The idea would be to implement `create_writer_physical_plan` https://github.com/apache/arrow-datafusion/blob/95ba48bd2291dd5c303bdaf88cbb55c79d395930/datafusion/core/src/datasource/file_format/arrow.rs#L51 Following the model of the CSV file format and https://github.com/apache/arrow-datafusion/blob/95ba48bd2291dd5c303bdaf88cbb55c79d395930/datafusion/core/src/datasource/file_format/csv.rs#L262-L290 Then add tests in copy.slt and arrow_file.slt ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
