The node will be created with a TTL that is updated via a refresh > operation. > The ZK quorum will watch this node similarly to the way that it watches for > session liveness; if the node is not refreshed within the TTL, it will expire. > QUESTIONS: > 1) Should we let the refresh operation set the TTL to a different base value? > 2) If so, should the setting of the TTL to a new base value cause a watch to > fire? > 3) Do we want to allow these nodes to have children or prevent this similar > to ephemeral nodes? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
