[jira] [Created] (BEAM-14144) Record JFR profiles when GC thrashing is detected

Steve Niemitz created BEAM-14144:
------------------------------------

             Summary: Record JFR profiles when GC thrashing is detected
                 Key: BEAM-14144
                 URL: https://issues.apache.org/jira/browse/BEAM-14144
             Project: Beam
          Issue Type: Improvement
          Components: runner-dataflow
            Reporter: Steve Niemitz
            Assignee: Steve Niemitz


It'd be useful for debugging GC issues in jobs to have allocation profiles when it was occurring.   In java 9+, JFR is included in the JDK, we could use that to record profiles when GC thrashing is detected.
