In some other part of the code I first checked if the future was done before adding a callback.</p> <p>I plan on removing the actor - it really isn't necessary plus we need to track the cohort state per transaction now that we have the pipelining - the current code assumes only one transaction at a time is undergoing 3PC since that's the way it was before pipelining.</p> <p>boron shortcuts: <a href="https://git.opendaylight.org/gerrit/55821" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/55821</a></p> <p>master: <a href="https://git.opendaylight.org/gerrit/55859" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/55859</a></p> <p>Agreed on killing DataTreeCohortActor.
