             Summary: FLIP-520: Simplify StructuredType handling
                 Key: FLINK-37861
                 URL: https://issues.apache.org/jira/browse/FLINK-37861
             Project: Flink
          Issue Type: New Feature
          Components: Table SQL / API, Table SQL / Planner
            Reporter: Timo Walther
            Assignee: Timo Walther


The motivation of the FLIP is to further extend the range of operations and 
expressions that are SQL serializable. Currently, it is not possible to declare 
a table using CREATE TABLE, creating structured types outside of UDFs, using a 
CAST, or declaring them as part of a @DataTypeHint function annotation. Table 
API’s table descriptors support structured types already.
