             Summary: Add NgRx reducers to perform parser and group changes in the store
                 Key: METRON-2134
                 URL: https://issues.apache.org/jira/browse/METRON-2134
             Project: Metron
          Issue Type: Sub-task
            Reporter: Tamas Fodor
            Assignee: Tamas Fodor


In NgRx, reducers are responsible for performing actual state changes in the global store. When something has been changed, it's the reducer's job to put it in the store in the appropriate way.

[https://ngrx.io/guide/store/reducers]

The implementation is pretty straightforward. Every reducer has the appropriate action to listen to and react to it. For example if we would like to start a parser, there must be a "start parser" action in order to trigger a state change that hasn't happened yet. It's the responsible who will update the store.
