Summary: 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
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)
