> qgen: create query profile emphasizing first_value / last_value testing
> -----------------------------------------------------------------------
>
> Key: IMPALA-3968
> URL: https://issues.apache.org/jira/browse/IMPALA-3968
> Project: IMPALA
> Issue Type: Task
> Components: Infrastructure
> Affects Versions: Impala 2.7.0
> Reporter: Michael Brown
> Priority: Major
>
> For directed testing of {{first_value / last_value \[ignore nulls\]}}, we
> need a query profile that emphasizes the use of those first_value and
> last_value analytic functions. The default query profile is too broad and is
> not likely to give us much coverage on those functions.
