> Addition of Indeterminate Collation Support
> -------------------------------------------
>
> Key: SPARK-47625
> URL: https://issues.apache.org/jira/browse/SPARK-47625
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 4.0.0
> Reporter: Mihailo Milosevic
> Priority: Major
> Labels: pull-request-available
>
> {{INDETERMINATE_COLLATION}} should only be thrown on comparison operations
> and memory storing of data, and we should be able to combine different
> implicit collations for certain operations like concat and possible others in
> the future.
> This is why we have to add another predefined collation id named
> {{INDETERMINATE_COLLATION_ID}} which means that the result is a combination
> of conflicting non-default implicit collations. Right now it would an id of
> -1 so it fail if it ever goes to the {{{}CollatorFactory{}}}.
