[jira] [Created] (ASTERIXDB-1579) Improve the type inference for lists with union item types

Yingyi Bu created ASTERIXDB-1579:
------------------------------------

             Summary: Improve the type inference for lists with union item types
                 Key: ASTERIXDB-1579
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-1579
             Project: Apache AsterixDB
          Issue Type: Improvement
            Reporter: Yingyi Bu
            Assignee: Yingyi Bu


Currently the accurate typing for ordered list with an UNION item type is not implemented.  We currently type it as [ANY]. This precludes the usage of WITH binding variables for field access path resolution in the consequent SELECT expression.
