[jira] [Created] (YUNIKORN-2147) Limit the number of concurrent event streams

Peter Bacsko created YUNIKORN-2147:
--------------------------------------

             Summary: Limit the number of concurrent event streams
                 Key: YUNIKORN-2147
                 URL: https://issues.apache.org/jira/browse/YUNIKORN-2147
             Project: Apache YuniKorn
          Issue Type: Sub-task
          Components: core - common
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


An active event stream means an open HTTP connection inside Yunikorn with goroutines. A normal REST call is closed immediately after the client was serviced. This is not the case here, Yunikorn can be attacked by creating too many event listeners.

We should limit the number of active connections. This can be a global limit, a per-host limit or both.
