          Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile)
    Affects Versions: 1.11.2
            Reporter: tinny cat
             Fix For: 1.11.3


with `debezium-json` and `canal-json`: 

Whether to capture the updates which don't change any monitored columns. This may happen if the monitored columns (columns defined in Flink SQL DDL) is a subset of the columns in database table.  We can provide an optional option， default 'true', which means all the updates will be captured. You can set to 'false' to only capture changed updates, but note this may increase some comparison overhead for each update event.
