Github user rtudoran commented on the issue:

    @fhueske  - you can check also the definition from the Calcite website
    Standard SQL features so-called “analytic functions” that can be used in the SELECT
clause. Unlike GROUP BY, these do not collapse records. For each record that goes in, one
record comes out. But the aggregate function is based on a window of many rows.

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please
contact infrastructure at infrastructure@apache.org or file a JIRA ticket
with INFRA.
