BlockMetadata stores data used by the Raft OSNs when coordinating with each other, to be serialized into block meta dta field and used after failres and restarts.

• repeated uint64 consenter_ids = 1

  Maintains a mapping between the cluster's OSNs and their Raft IDs.

• uint64 next_consenter_id = 2

  Carries the Raft ID value that will be assigned to the next OSN that will join this cluster.

• uint64 raft_index = 3

  Index of etcd/raft entry for current block.

ClusterMetadata encapsulates metadata that is exchanged among cluster nodes

• repeated uint64 active_nodes = 1

  Indicates active nodes in cluster that are reacheable by Raft leader

ConfigMetadata is serialized and set as the value of ConsensusType.Metadata in a channel configuration when the ConsensusType.Type is set "etcdraft".

• repeated Consenter consenters = 1

• optional Options options = 2

Consenter represents a consenting node (i.e. replica).

Used in: ConfigMetadata

• string host = 1

• uint32 port = 2

• bytes client_tls_cert = 3

• bytes server_tls_cert = 4

Options to be specified for all the etcd/raft nodes. These can be modified on a per-channel basis.

Used in: ConfigMetadata

• string tick_interval = 1

  time duration format, e.g. 500ms

• uint32 election_tick = 2

• uint32 heartbeat_tick = 3

• uint32 max_inflight_blocks = 4

• uint32 snapshot_interval_size = 5

  Take snapshot when cumulative data exceeds certain size in bytes.
