The stream state and replica info is only guaranteed to be accurate when returned by the leader of a given stream. This new option returns stream details only for the stream in which the server is the leader for that stream. For systems with many streams this can significantly reduce the amount of data returned when scraping across all servers since non-leader details will likely be ignored.

Thinking about this a bit more, for the cases that a leader is not elected/available for some reason, is the output of JSZ to not set the cluster leader field? If so, then having this option set would never return those cases by any of the servers. |
