Lars Volker commented on IMPALA-7644:
-------------------------------------

What's the target version for this? I think it would be better to get proper testing done before the next release instead of adding another temporary flag.

> 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.
