Yes, thank you @hhhizzz ! I have been quite busy recently helping @etseidl get the new parquet metadata decoder in. See the following tickets if you are interested - https://github.com/apache/arrow-rs/issues/8441 - https://github.com/apache/arrow-rs/issues/5854 maybe @zhuqi-lucas also has some ideas / time to help as he had several good PRs One thing I tried to do to help here is this PR: - https://github.com/apache/arrow-rs/pull/7537 I think the trickiest part of this project is not degrading performance for the existing cases where the current `RowSelection` is really good (namely representing large contiguous selections) One thing that @lwwmanning mentioned that works pretty well in Vortex was to use a `LazyLock` to hold an alternate predicate representations and computing it on demand. -- This is an automated message from the Apache Git Service.
