             Summary: Fix ANY type serialization
                 Key: FLINK-12726
                 URL: https://issues.apache.org/jira/browse/FLINK-12726
             Project: Flink
          Issue Type: Sub-task
          Components: Table SQL / API
            Reporter: Timo Walther
            Assignee: Timo Walther


Every logical type needs to be string serializable. In old versions we used Java serialization logic for it. Since an any type has no type information anymore but just type serializer, we can use the snapshot to write out an any type into properties in a backward compatible way.

However, the current serialization logic is wrong.
