kcp migration cutover lag-check

kcp migration cutover lag-check¶

Show mirror topic lag for the cluster link

Synopsis¶

Interactive TUI that displays mirror topic lag for the cluster link. Run in a terminal. Press q (or ctrl+c) to quit, p to toggle partition details, r to refresh, +/- to adjust interval, arrow keys or j/k to scroll.

Everything it needs — the destination REST endpoint, cluster id, link name and credentials — comes from the migration manifest, so this command works before 'kcp migration cutover execute' has ever run. The credentials are the cluster-link REST leg (spec.clusterLink.linkCredentials), honoured in whatever form the manifest resolves — api_key, basic, bearer, or mtls. lag-check never dials the source or destination Kafka legs directly.

It always shows every mirror topic on the link; the declared migration's topicGroup does not narrow the view.

Before the view opens, kcp reads the cluster link (15s timeout); if that fails, the command exits with an error.
