             Summary: Write full changelog to Paimon Sink.
                 Key: FLINK-37352
                 URL: https://issues.apache.org/jira/browse/FLINK-37352
             Project: Flink
          Issue Type: Improvement
          Components: Flink CDC
    Affects Versions: cdc-3.3.0
            Reporter: Yanquan Lv
             Fix For: cdc-3.4.0


Paimon streaming write can continuously produce the latest changes for 
streaming read.
By specifying {{{}'changelog-producer' = 'input'{}}}, Paimon writers rely on 
their inputs as a source of complete changelog. All input records will be saved 
in separated changelog files and will be given to the consumers by Paimon 
sources.

However, currently we have only inserted the update after data for Update, so 
the generated changelog is incomplete.
