**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** The `FileReader` currently doesn't support projection to skip reading/decoding certain columns. This could be used by engines lole DataFusion to make the Arrow file reader more efficient. **Describe the solution you'd like** Support an optional `Vec<usize>` parameter to configure the column indexes in the reader. **Describe alternatives you've considered** **Additional context** See support in arrow2 https://docs.rs/arrow2/latest/arrow2/io/ipc/read/struct.FileReader.html -- This is an automated message from the Apache Git Service.
