Meeting summary --------------- * general updates (colindixon, 17:05:00) * What’s going on in Clustering? (moizer, 17:05:16) * tony says they are in the process of moving people from composite nodes to normalized nodes (colindixon, 17:05:37) * clustering updates (colindixon, 17:05:56) * right now the work going on in clustering is in the form of performance (colindixon, 17:06:18) * there has been a lot of prior work on stability (both in single-node and 3-node clusters) (colindixon, 17:06:45) * performance work is focused on the “DS” benchmark in coretutorials as well as some apps, e.g., bgpcep (colindixon, 17:07:08) * some bugs crop up from time-to-time, but mostly focused on performance for now (colindixon, 17:07:30) * the next major thing would be moving to using clustering by default (with a single-node) (colindixon, 17:07:56) * LuisGomez says he’s planning to do testing to figure out if we can make the cut-over without issues (colindixon, 17:08:20) * LuisGomez says last he checked, there were issues in the l2switch and maybe some scale-testing (colindixon, 17:08:38) * moizer says the hope is that if you cut over to using clustering by default, it will push people to fix issues faster (colindixon, 17:09:10) * devinavery asks if there’s a way to see the known issues with clustering, e.g., buzilla (colindixon, 17:11:48) * tony says any bugs with a clustering prefix in the MD-SAL is the right things (colindixon, 17:12:10) * tony asks that the bug list not be posted to the wiki, but only a link to the query so that information stays in bugzilla (colindixon, 17:12:38) * ACTION: moizer to post a link to the open bugs in clustering (colindixon, 17:13:11) * LINK: https://bugs.opendaylight.org/buglist.cgi?bug_severity=blocker&bug_severity=critical&bug_severity=major&bug_severity=normal&bug_severity=minor&bug_severity=trivial&component=General&component=mdsal&component=netconf&component=restconf&f1=target_milestone&f2=cf_target_milestone&j_top=OR&known_name=MD-SAL%3A%20Bugs%3A%20Helium&list_id=24959&o1=substring&o2=substring&product=controller&product=yangtools&query_based_on=MD-SAL%3A%20Bu (ttkacik, 17:13:42) * LINK: https://wiki.opendaylight.org/view/OpenDaylight_Controller:Clustering (moizer, 17:14:03) * migrating from composite node to normalized node (colindixon, 17:14:53) * people are working on moving from composite nodes (the old DOM interface to the MD-SAL) since they proved inefficient for what was actually being done in OpenDaylight (colindixon, 17:15:36) * the new APIs are based on composite nodes which are more performant (colindixon, 17:15:52) * the most performance critical elements (data store, and RESCONF access) were moved during Helium (colindixon, 17:16:23) * as stated during the last Lithium release cross-project IRC meeting, the controller project and yangtools are formally moving everything away from composite nodes (colindixon, 17:17:53) * moizer asks if they will be expected to move or if tony and others will be able to do it (colindixon, 17:18:09) * tony says that he and a few others plan to do all of the migration for people (colindixon, 17:18:28) * tony says that this should result in there being a lot less code as a result of this because there will only be one set of code paths (colindixon, 17:18:59) * there *may* be some bugs, but they’re trying hard to avoid any regressions (colindixon, 17:19:20) * LuisGomez asks when we should be expecting these changes (colindixon, 17:19:38) * tony says they should be landing on Monday (colindixon, 17:19:49) * colindixon asks if there will be a reduction in the code and complexity of the code for serialization since he’s had trouble with them in the past (colindixon, 17:22:21) * tony says that is is intended and should be a lot easier that before because they were designed to be more usable by outside people (colindixon, 17:23:50) * he also notes that the only projects outside of YANG Tools that use it are controller and ttp (colindixon, 17:24:04) * now the process should be more about producing translation pipelines, which should be easier (colindixon, 17:26:21) * tony says they will be maintaining sample code for using them as well (they even have a way to get the snippets cut out and put into AsciiDoc) (colindixon, 17:27:20) * devinavery asks for any links to bugs, etc. (colindixon, 17:27:28) * tony says that there should be links to “tree views” in bugzilla from the YANG tools and controller Lithium release plans (colindixon, 17:27:53) * LINK: https://wiki.opendaylight.org/view/OpenDaylight_Controller:Lithium:Release_Plan controller release plan (colindixon, 17:28:42) * LINK: https://wiki.opendaylight.org/view/YANG_Tools:Lithium:Release_Plan yang tools release plan (colindixon, 17:28:51) Meeting ended at 17:28:54 UTC.
