             Summary: Add ability to filter events on the subscriber stream for Master API.
                 Key: MESOS-6552
                 URL: https://issues.apache.org/jira/browse/MESOS-6552
             Project: Mesos
          Issue Type: Improvement
            Reporter: Anand Mazumdar


Currently, the v1 Master API allows an operator to subscribe to events happening on their clusters e.g., any time a new task is launched/updated. However,  there is no ability currently for a subscriber to express its interest in a particular subset of events on the master e.g, only in task add/updated events

This would also take care of use cases where a subscriber would be short lived i.e., is only interested to see if a particular task has been launched on the cluster by the framework and then close its connection thereafter. Currently, such subscribers also receive the entire snapshot of the cluster via the {{SNAPSHOT}} events that can be rather huge for production clusters (we also don't support compression on the stream yet). Such subscribers in the future would be able to opt out of this event.
