How long can a worker run without a leader

I am in charge of documenting our disaster recovery and high-availability efforts. One of the questions that came up is whether the worker nodes will cease to function (or reduce functionality) when the leader node disappears for a prolonged time. If so, how much time do we have until we must resurrect the leader?

Workers will continue receiving data from push sources, and some pull sources will continue working as well, but may not be optimal. Many pull sources (like REST collectors) will stop working as the Leader coordinates their execution across the Group.

I don’t think there is a set limit for how long Workers will run Leaderless. From experience I can say at least a day.

How about the license? Will the workers eventually fall back to a free license when the leader is gone? The key information I am looking for is how much time we can run without a leader before the workers change their behavior.

No, they will continue operating based on the last license info they saw. I’m not sure there is a limit here, but as I said from experience, at least a day.
