             Summary: Cluster initialization flow
                 Key: IGNITE-14414
                 URL: https://issues.apache.org/jira/browse/IGNITE-14414
             Project: Ignite
          Issue Type: Bug
            Reporter: Vyacheslav Koptilin


For a cluster to become operational, the metastorage instance must be initialized first. The initialization command chooses a set of nodes (normally, 3 - 5 nodes) to host the distributed metastorage Raft group. When a node receives the initialization command, it either creates a bootstrapped Raft instance with the given members (if this is a metastorage group node), or writes the metastorage group member IDs to the vault as a private system-level property.

After the metastorage is initialized, components start to receive and process watch events, updating the local state according to the changes received from the watch.
