show-raft#
Shows BDR Raft (consensus protocol) details.
Synopsis#
Shows 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 show-raft [flags]
Options#
No specific command options. See Global Options for global options.
Examples#
Show Raft details#
In this example, there is a multi-group cluster with subgroup Raft and with witness, logical standby, subscriber-only nodes. Note that logical standby and subscriber-only nodes don’t have Raft voting rights, unlike data or witness nodes.
$ pgd show-raft
