Ming Li created FLINK-32001:
-------------------------------
Summary: SupportsRowLevelUpdate does not support returning only a
part of the columns.
Key: FLINK-32001
URL: https://issues.apache.org/jira/browse/FLINK-32001
Project: Flink
Issue Type: Improvement
Components: Table SQL / Runtime
Affects Versions: 1.17.0
Reporter: Ming Li
[FLIP-282|https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=235838061]
introduces the new Delete and Update API in Flink SQL. Although it is
described in the documentation that in case of {{partial-update}} we only need
to return the primary key columns and the updated columns.
But in fact, the topology of the job is {{{}source -> cal ->
constraintEnforcer -> sink{}}}, and the constraint check will be performed in
the operator of {{{}constraintEnforcer{}}}, which is done according to index,
not according to column. If only some columns are returned, the constraint
check is wrong, and it is easy to generate
{{{}ArrayIndexOutOfBoundsException{}}}.
