I see. Thanks for that explanation. Here's an example: given a row group, containing pages: - page 0 (min: 1, max: 5) - page 1 (min: 6, max: 9) - page 2 (min: 10, max: 16) - page 3 (min: 17, max: 22) We would like to read a range of data from 7 to 14. We should be able to use column indexes and page indexes to narrow the pages down to just page 1 and page 2, and read those pages. I think parquet-go (https://github.com/parquet-go/parquet-go) implemented an API to seek to a row number within the row group and an API to read x number of rows from there. -- This is an automated message from the Apache Git Service.
