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 jobĀ 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{}}}. -- This message was sent by Atlassian Jira (v8.20.10#820010)
