wonook opened a new pull request #215: [NEMO-373] Optimize with DAG Patterns
URL: https://github.com/apache/incubator-nemo/pull/215
 
 
   JIRA: [NEMO-373: Optimize with DAG Patterns](https://issues.apache.org/jira/projects/NEMO/issues/NEMO-373)
   
   **Major changes:**
   - Adds Pattern metadata to the DB to recognize different patterns
   - Adds logic to sort execution properties based on the patterns.
   - Adds the ability to recognize data given based on patterns to make them into the newly
learned execution properties.
   
   **Minor changes to note:**
   - Registration of user arguments, which had been missed out by accident.
   - Adds `toString()` methods to `OperatorVertex` and `SourceVertex` to pretty-print them
and to recognize identical source/transforms as equal ones.
   
   **Tests for the changes:**
   - Test added with the DB enabled
