Benjamin Lerer resolved CASSANDRA-13411.
----------------------------------------
Resolution: Invalid
> CQL query using the MAX function returns resultset with Row(null, null ...)
> if data is not found
> ------------------------------------------------------------------------------------------------
>
> Key: CASSANDRA-13411
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13411
> Project: Cassandra
> Issue Type: Bug
> Components: CQL
> Environment: 3.10
> Reporter: Andrew Efimov
> Priority: Minor
>
> CQL query using the MAX function returns resultset with rows.size=1 if data
> is not found. And Row has only null values.
> {{SELECT id, value, MAX(date) FROM table WHERE id = "13411"}}
> If table does not have row by {{id = "13411"}} then session returns ResultSet
> with Rows.size = 1 and Row(null, null, null).
> This is a problem to determine whether or not a data has actually been exist.
> I did not check other aggregation functions.
