**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** <!-- A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] (This section helps Arrow developers understand the context and *why* for this feature, in addition to the *what*) --> Currently we make use of the Apache thrift crate for encoding and decoding Parquet metadata. This has served us well, but there are a few problems: * The performance is sub-optimal - https://github.com/apache/arrow-datafusion/discussions/7737#discussioncomment-7186343 * It does not appear to be maintained anymore - https://issues.apache.org/jira/browse/THRIFT-5640 * https://docs.rs/databend-thrift/latest/databend_thrift/ * https://docs.rs/tent-thrift/latest/tent_thrift/ **Describe the solution you'd like** <!-- A clear and concise description of what you want to happen. --> Parquet requires a very limited portion of the thrift specification, only making use of the compact encoding, and none of the protocol functionality. It should be relatively straightforward to support this subset with a custom implementation. **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.
