> Support conditional traits for PTFs
> -----------------------------------
>
> Key: FLINK-39392
> URL: https://issues.apache.org/jira/browse/FLINK-39392
> Project: Flink
> Issue Type: New Feature
> Components: Table SQL / API
> Affects Versions: 2.2.0
> Reporter: Gustavo de Morais
> Assignee: Gustavo de Morais
> Priority: Major
> Labels: pull-request-available
> Fix For: 2.3.0
>
>
> We'd like to make PTF traits configurable so we can have multiple versions
> depending on how they are configured by the user.
> The first suggestion: introduce a declarative addTraitWhen API on
> StaticArgument that allows table argument traits to vary based on the SQL
> call context (e.g., whether PARTITION BY is provided or scalar argument
> values). This replaces the static
>
>
>
> - As the first use case, TO_CHANGELOG now supports optional PARTITION BY:
>
> - With PARTITION BY: set semantics (co-located parallel execution)
