[jira] [Created] (FLINK-13200) Improve the generated code for if statements

Liya Fan created FLINK-13200:
--------------------------------

             Summary: Improve the generated code for if statements
                 Key: FLINK-13200
                 URL: https://issues.apache.org/jira/browse/FLINK-13200
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / Planner
            Reporter: Liya Fan
            Assignee: Liya Fan


In the generated code, we often code snippet like this:

 

if (true) {
  acc$6.setNullAt(1);
} else {
  acc$6.setField(1, ((int) -1));;
}

Such code impacts the code readability, and increases the code size, making it more costly for compiling and transferring through network.

 

In this issue, we remove such useless if conditions.
