Subject [jira] [Created] (FLINK-3792) RowTypeInfo equality should not depend on field names
Date Wed, 20 Apr 2016 14:35:25 GMT
Vasia Kalavri created FLINK-3792:
------------------------------------

             Summary: RowTypeInfo equality should not depend on field names
                 Key: FLINK-3792
                 URL: https://issues.apache.org/jira/browse/FLINK-3792
             Project: Flink
          Issue Type: Bug
          Components: Table API
    Affects Versions: 1.1.0
            Reporter: Vasia Kalavri


Currently, two Rows with the same field types but different field names are not considered
equal by the Table API and SQL. This behavior might create problems, e.g. it makes the following
union query fail:

{code}
SELECT STREAM a, b, c FROM T1 UNION ALL 
(SELECT STREAM d, e, f FROM T2 WHERE d < 3)
{code}

where a, b, c and d, e, f are fields of corresponding types.

{code}
Cannot union streams of different types: org.apache.flink.api.table.Row(a: Integer, b: Long,
c: String) and org.apache.flink.api.table.Row(d: Integer, e: Long, f: String)
{code}
