[jira] [Created] (FLINK-31350) Support Calcite's 1.30+ UnknownType

Sergey Nuyanzin created FLINK-31350:
---------------------------------------

             Summary: Support Calcite's  1.30+ UnknownType
                 Key: FLINK-31350
                 URL: https://issues.apache.org/jira/browse/FLINK-31350
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
    Affects Versions: 1.18.0
            Reporter: Sergey Nuyanzin


In 1.30 in Calcite https://issues.apache.org/jira/browse/CALCITE-4872 there has been introduced a new type UNKNOWN which is similar to NULL however is not nullable by default and as a result breaks some tests.

 

I guess a similar type should be introduced in Flink to support it
