#opendaylight-clustering: clustering_hackers

Meeting summary

1. 1. Agenda : bugs, commits, sfc, bandwidth (moizer, 14:59:57)
   2. meeting cannot exceed 1 hr - same meeting is used for MD-SAL call (moizer, 15:00:23)
   
   
2. bugs (moizer, 16:01:30)
   1. Philip to try reproducing bug 2892 (moizer, 16:02:22)
   2. Moiz to try reproducing bug 2860 (moizer, 16:02:54)
   3. Tom to work on OpenFlow related issues (moizer, 16:03:17)
   4. OpenFlow apps cannot be used without modification in a cluster (moizer, 16:04:10)
   5. Only apps which are on the inventory-operational node should be made active (moizer, 16:04:36)
   6. The RoleChangeNotification can be used for this purpose (moizer, 16:04:59)
   7. Anil/Kamal need to package up RoleChangeNotification as a yang notification so that it is easier to consume by the rest of the ODL eco-system (moizer, 16:05:38)
   8. rovarga says the new openflow changes will not help solve the problem of openflow clustering in Lithium however it is being setup for better scalability as it allows the data for each device to be stored in it’s own shard (moizer, 16:07:50)
   
   
3. commits (moizer, 16:08:01)
   1. rovarga promises to add unit tests later for https://git.opendaylight.org/gerrit/#/c/16690/ - so we will move forward with merging the changes after final review (moizer, 16:09:00)
   2. commits for the CDS do need to be accompanied with unit tests (moizer, 16:09:56)
   
   
4. performance improvement (moizer, 16:10:23)
   1. DataTreeCandidate provides a delta of changes that were done to a DataTree in a transaction (moizer, 16:11:05)
   2. Since DataTreeCandidate is likely more compact than the list of modifications made to a DataTree it will be more efficient to persist and replicate the DataTreeCandidate (moizer, 16:12:41)
   3. Will continue further discussion on this topic in the next hackers call (moizer, 16:13:18)
