This means that in a stable system, there would be less snapshot sent and more in-mem log entries</p> <p>For a follower, the real snapshot should follow the replicatedToAllIndex sent via Leader's AppendEntries</p> <p>Operating System: All<br/> Platform: All</p> CONTROLLER-1144

Clustering: Initiate snapshot interferes with fake snapshot

Bug Resolved Done Kamal Rameshan Kamal Rameshan Mon, 9 Feb 2015 19:54:25 +0000 Mon, 30 Mar 2015 21:14:13 +0000 Mon, 30 Mar 2015 21:14:13 +0000 Post-Helium mdsal 0 4 <p>Also take care of InitiateSnapshots not getting kicked in more than once</p> <p>The solution can be divided into following 5 parts</p> <p>1. Avoid Initiate Snapshot happening more than once</p> <p>2. Fake snapshot should not take place when an initiate has been initiated</p> <p>3. Capture snapshot currently clears the log from lastApplied. It should resemble fake snapshot by making use of the replicatedToAllIndex. Followers should have the similar logic</p> <p>4. Remove the Initiate snapshot message</p> <p>5. Refactor to consolidate the fake and real snapshot logic to have these in one place.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/15091/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/15091/</a> - covers 1 and 2</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/15131/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/15131/</a> - covers 3</p> <p><a href="https://git.opendaylight.org/gerrit/15239" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/15239</a> - covers 4</p> <p>Refactoring to cover 5</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/15610" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/15610</a><br/> <a href="https://git.opendaylight.org/gerrit/#/c/15611" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/15611</a></p> Development External issue ID 2692 External issue URL Issue Type ODL SR Target Milestone Priority Rank 0|i02orb:
