From: Rajesh_Sindagi Date: Tue, 20 Oct 2015 22:38:41 +0000 (-0700) Subject: BUG-2187: Add Server - Leader Implementation X-Git-Tag: release/beryllium~230 X-Git-Url: https://git.opendaylight.org/gerrit/gitweb?p=controller.git;a=commitdiff_plain;h=4e186d6e4a9c84482dc74aee353e12a12f6728a7 BUG-2187: Add Server - Leader Implementation Processes addServer request from the follower, forwards the request to the shard leader, if not the leader. The follower shard replica data is brought to sync with leader by installing the snapshot from the shard leader. On sucessful application of snapshot data, this voting but not initialized member is transitioned to voting member. New server configuration is persisted and replicated to majority of the followers and responds back with OK message to the shard follower. In case where the leader is unable to sync data to the follower in a configured time period, TIMEOUT message is responded back to the shard follower without adding/persisting the new server configuration.
