**Is your feature request related to a problem or challenge? Relate #2965 https://github.com/apache/arrow-datafusion/blob/193fc3b4549ed40a08218b744388f9211605ab53/datafusion/core/src/physical_plan/file_format/file_stream.rs#L218-L228 Before i add the cost time metric here. But there are two sub future or stream under `self.poll_inner(cx)` one is a future to read parquet metadata https://github.com/apache/arrow-datafusion/blob/193fc3b4549ed40a08218b744388f9211605ab53/datafusion/core/src/physical_plan/file_format/file_stream.rs#L162-L165 another is: for read and decode data https://github.com/apache/arrow-datafusion/blob/193fc3b4549ed40a08218b744388f9211605ab53/datafusion/core/src/physical_plan/file_format/file_stream.rs#L177-L181 If these future are not ready will return `Poll::Pending`, which will make the task blocked and need someone wake itself. So we miss the read_meta time and reading time. **Describe the solution you'd like** A clear and concise description of what you want to happen. **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
