Subject [jira] [Commented] (APEXCORE-497) Create a DelayNode for DelayOperator
Date Fri, 22 Jul 2016 18:02:20 GMT

Thomas Weise commented on APEXCORE-497:
---------------------------------------

Given there already was a discussion about this topic and the rationale for the implementation
explained, I don't find this JIRA without context helpful. At the very least it should justify
why the proposed solution is better and it would be worthwhile working on it.

> One of the design elements I have seen in Apex is, while deploying only required objects
are deployed. For example Stream persistence reservoir was created only when it is required.
So in the same spirit, we can have the DelayNode for Delay Operators.
> Delay Operator related changes happen for the control tuples in GenericNode.
> Implementation Idea: 
> 1. Create functions for handling each control tuples in Generic Node
> 2. DelayNode extends GenericNode
> 3. Overrides the required functions created in step 1.
> 4. During deployment based on the operator type, create the required Node.
