Lists BDR Raft (consensus protocol) details

Synopsis

Lists BDR Raft (consensus protocol) details such as Raft instance id, Raft state (leader, follower), and Raft term. If Raft is enabled at subgroup level, then that subgroup's Raft instance is also shown.

In some cases, such as network partition, output might vary based on the node to which the CLI is connected.

pgd raft list [flags]

Examples

Viewing Raft details

In this example, we have a multi-group cluster with a subgroup Raft and a witness, logical standby, and subscriber-only nodes.

Note: Unlike data or witness node, logical standby and subscriber-only nodes don't have Raft voting rights (see the Voting Nodes column).
