Sorry, I meant it won't be available in 3.1.0, we plan to deliver it in 3.2.0.
PS: oops, thanks!

> Key: IMPALA-7644
> URL: https://issues.apache.org/jira/browse/IMPALA-7644
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
>
> Currently there is no released Impala version that can write the Parquet page index:
> [https://github.com/apache/parquet-format/blob/master/PageIndex.md]
> However, the current Impala master writes the page index since IMPALA-5842, but cannot read it.
> I think we should hide the write path with a feature flag until Impala is able to read it back and has better test coverage on it.
