  2. Current Reconciliation (abhijitkumbhare, 16:15:58)
    1. Currently a one shot read from the datastore of tables, groups, flows, meters - and provisionally sequentially (abhijitkumbhare, 16:18:29)
    2. its a thread-pool size of 4 , so 4 reconsiliations can happen in parallel for 4 devices (shuva, 16:22:07)
    3. controller stale marking implemented so that when someone deletes a flow on the controller with the switch is not there, its deleted on a switch connected (shuva, 16:24:01)
    4. provisioning is a separate flow of control as compared to reconsiliation (shuva, 16:24:37)
    5. so both can go in parallel, since we donot have any checkpointing/boundary mechanism in place (shuva, 16:25:19)

  3. Bundles & resync (abhijitkumbhare, 16:26:42)
    1. https://wiki.opendaylight.org/view/OpenDaylight_OpenFlow_Plugin:Hitless_resync (abhijitkumbhare, 16:26:59)
    2. Why bundles based reconciliation: to reliably & hitlessly cleanup the state of switch at the connection/reconnection (abhijitkumbhare, 16:35:10)
    3. Discussions about what is mandatory and what is optional on the switch regarding bundles (abhijitkumbhare, 16:51:42)
    4. In particular - the spec is unclear about how many bundles the switch must support (abhijitkumbhare, 16:52:19)

  4. Regression Tests for Model cleanup, split connection layer (abhijitkumbhare, 16:59:01)
    1. Some infra issues present currently (abhijitkumbhare, 16:59:34)
    2. tomasslusny & jbacigal to send the patch numbers to LuisGomez (abhijitkumbhare, 17:00:05)

  5. Clustering Acceptance Tests thread by Vratko (abhijitkumbhare, 17:00:37)
    1. https://git.opendaylight.org/gerrit/#/c/51304/ (tomasslusny, 17:00:40)
