--------------------------------------------
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.
