**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** While investigating #6310 I noticed that when a page contains only null values, min and max for that page will be set to `vec![0; 1]`. Because of this, a byte array of length 1 will be written. Instead an empty vec should be passed so spurious min/max values are not produced. **Describe the solution you'd like** Rather than `vec![0; 1]`, `vec![]` should be passed to `ColumnIndexBuilder::append`. This will reduce the column index size a tiny bit. **Describe alternatives you've considered** It could be the current behavior is desired, so no change would be necessary. **Additional context** The current behavior isn't a bug, but is a little wasteful. -- This is an automated message from the Apache Git Service.
