Hello I am excited to say there is a proposed async parquet reader contribution to arrow-rs ready for review [1].
It adds a requirement for some of the core parquet traits to be `Send` and/or `Sync` -- I don't think this is likely to be a problem for most usecases but I wanted to highlight the issue so others could try it or comment out before we create a new release. Thanks, Andrew [1] https://github.com/apache/arrow-rs/pull/1154
