--------------------------------

             Summary: Allow heap dumps on OOM to be disabled (default)
                 Key: BEAM-87
                 URL: https://issues.apache.org/jira/browse/BEAM-87
             Project: Beam
          Issue Type: Bug
          Components: runner-core
            Reporter: Mark Shields
            Assignee: Frances Perry


Runners may wish to save a heap dump on OOM. (The Google runner does so). However since heap
dumps can be large some runners may struggle to save them. (The Google runner saves heap dumps
on the vm's 'boot' disk, which is typically only 20GB). We should allow users to opt-in to
heap dumps, at which point they can also ensure their environment is provisioned to accept
them. (Eg for the Google runner, increase the boot disk size.)
