The digest coordinator controls which nodes digest which partitions in the ingest queue. It is a critical component for failover when digest nodes stop or crash. A coordinator with high latency to global nodes can make poor decisions about partition leadership assignments. This limit prevents such a node from acting as coordinator.

To set the limit at boot time, use the MAX_GLOBAL_LATENCY_MS_FOR_DIGEST_COORDINATOR environment variable. To change the limit while the cluster runs, set the MaxGlobalLatencyMsForDigestCoordinator dynamic configuration parameter. LogScale keeps the dynamic configuration value between the minimum and the maximum.
