A PoC for parquet-rs is available [here](https://github.com/apache/arrow-rs/pull/7408). I've also demonstrated that the current state of affairs doesn't allow page pruning for floating point columns in datafusion ([issue](https://github.com/apache/datafusion/issues/15812), [fix](https://github.com/apache/datafusion/pull/15821)). Finally, I have a fork of datafusion that uses the parquet-rs changes to re-enable pruning (https://github.com/etseidl/datafusion/tree/total_order_pruning). Given @wgtmac's java PoC (https://github.com/apache/parquet-java/pull/3191) I think we have the necessary implementations and justification to move this PR forward. Should there be further discussion on the dev list or can we begin a vote on this? @JFinis @mapleFU @emkornfield @gszadovszky @pitrou @Mytherin -- This is an automated message from the Apache Git Service.
