[jira] [Created] (FLINK-31289) Default aggregate-function for field can be last_non_null_value

Jingsong Lee created FLINK-31289:
------------------------------------

             Summary: Default aggregate-function for field can be last_non_null_value
                 Key: FLINK-31289
                 URL: https://issues.apache.org/jira/browse/FLINK-31289
             Project: Flink
          Issue Type: Improvement
          Components: Table Store
            Reporter: Jingsong Lee
             Fix For: table-store-0.4.0


At present, when aggfunc is not configured, NPE will be generated. When the table is oriented to many fields, the configuration will be more troublesome.

We can give the field the default aggfunc, such as last_ non_ null_ Value, which is consistent with the partial-update table.
