Stefan Egli resolved SLING-3390. -------------------------------- Resolution: Won't Fix Marking as won't fix. I don't see any need for this. Esp give complete silence in discovery.oak for tarMk. > [discovery] silence discovery.impl when in single-node case > ----------------------------------------------------------- > > Key: SLING-3390 > URL: https://issues.apache.org/jira/browse/SLING-3390 > Project: Sling > Issue Type: Improvement > Components: Extensions > Affects Versions: Discovery Impl 1.0.2 > Reporter: Stefan Egli > > As proposed on the list at [0] we have two optimizations (actual one, the > second one includes the first one) as described in SLING-3389 that are rather > straight forward. > There is a third optimization which would silence the discovery.impl > entirely, if it realizes that it is in fact alone. > The referred details extracted from [0] are: > "What could be done for level 3: > a) at startup the behavior is as is today, cluster-ready, writing > repository-heartbeats as configured > b) this is done for a configured amount of time at least, eg for 5 > minutes (exploring phase) - the idea of this being to avoid any > race-conditions of two nodes starting simultaneously > c) if after this time, the node realizes, that it is alone (and no-one > joined or left during this time), it assumes that it is indeed in a > standalone setup and stops sending heartbeats (solitude phase) > d) if another node starts up in the same cluster, it would as normal > start doing these heartbeats for a few minutes (exploring phase) - giving > the original node time to wake up to the idea that it was never alone > (alien phase) - at which point it quickly starts to go back to sending > heartbeats and voting and all those things (party phase) > phase d) is obviously slightly tricky .. > " > This is considered a nice-to-have at the moment, but here's the ticket for > reference to reconsider later. > [0] http://markmail.org/thread/2ev5sy3b3mr5klc5 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
