Subject [jira] [Created] (FLINK-947) Add support for "Named Datasets"
Date Wed, 18 Jun 2014 12:14:04 GMT
Aljoscha Krettek created FLINK-947:
--------------------------------------

             Summary: Add support for "Named Datasets"
                 Key: FLINK-947
                 URL: https://issues.apache.org/jira/browse/FLINK-947
             Project: Flink
          Issue Type: New Feature
          Components: Java API
            Reporter: Aljoscha Krettek
            Assignee: Aljoscha Krettek
            Priority: Minor


This would create an API that is a mix between SQL like declarativity and the power of user
defined functions. Example user code could look like this:

{code:Java}
NamedDataSet one = ...
NamedDataSet two = ...
NamedDataSet result = one.join(two).where("key").equalTo("otherKey")
  .project("a", "b", "c")
  .map( (UserTypeIn in) -> return new UserTypeOut(...) )
  .print();
{code}
