**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** Suggested by @ParadoxShmaradox ON #1191 In analytics systems, parquet files are passed around between different systems, so the more metadata is written by the rust implementation of parquet, the better other systems may be able to handle it. One such type of metadata is `PageIndex` https://github.com/apache/parquet-format/blob/master/PageIndex.md Specifically, I believe this is called a `ColumnIndex` and `OffsetIndex` in parquet-format: https://github.com/apache/parquet-format/blob/master/src/main/thrift/parquet.thrift#L938-L971 https://github.com/apache/parquet-format/blob/master/src/main/thrift/parquet.thrift#L926-L932 Which is used to speed up queries in certain systems -- for example https://blog.cloudera.com/speeding-up-select-queries-with-parquet-page-indexes/ **Describe the solution you'd like** 1. Write `PageIndex` structures into files created by parquet-rs (specif 2. Provide access to reading `PageIndex` from the parquet metadata structures Note that if creating the `PageIndex` structures is too expensive, their creation could be optional and controlled via options. **Describe alternatives you've considered** A clear and concise description of any alternative solutions or features you've considered. **Additional context** Original request here https://github.com/apache/arrow-rs/issues/1191#issuecomment-1126814290 -- This is an automated message from the Apache Git Service.
