**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** - Part of https://github.com/apache/arrow-rs/issues/8000 The current `ParquetMetadataReader` intermixes three things: 1. The state machine for decoding parquet metadata (footer, then metadata, then (optional) indexes) 2. orchestrating IO (aka calling read, etc) 3. Decoding thrift encoded byte into objects This makes it almost impossible to add features like "only decode a subset of the columns in the ColumnIndex" and other potentially advanced usecases **Describe the solution you'd like** Now that we have a "push" style API for metadata decoding that avoids IO, I would like to separate out these three parts so that we can add better features **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.
