[jira] [Created] (FLINK-1710) Expression API Tests take very long

Stephan Ewen created FLINK-1710:
-----------------------------------

             Summary: Expression API Tests take very long
                 Key: FLINK-1710
                 URL: https://issues.apache.org/jira/browse/FLINK-1710
             Project: Flink
          Issue Type: Bug
          Components: Expression API
    Affects Versions: 0.9
            Reporter: Stephan Ewen
            Assignee: Aljoscha Krettek
             Fix For: 0.9


The tests of the Expression API take an immense amount of time, compared to the other API tests.

Is that because they execute on large (generated) data sets, because the program compilation overhead is high, or because there is an inefficiency in the execution still?
