> Enhance decoders to support value-skipping

> Key: IMPALA-7979
> URL: https://issues.apache.org/jira/browse/IMPALA-7979
> Project: IMPALA
> Issue Type: Sub-task
> Reporter: Zoltán Borók-Nagy
> Assignee: Zoltán Borók-Nagy
> Priority: Major
>
> When the parquet scanner can use the page index it is sometimes needed to
> skip values from the pages. We can just drop these values since we'll never
> need them.
> The decoders don't support value-skipping at the moment, therefore we have to
> decode each and every value even if we know that we will never need many of
> them.
> The decoders should have methods for value-skipping to make scanning more
> efficient.
