Observers

Observer configuration controls retry behavior, timeouts, and watchdog monitoring for observer subscribers.

Example configuration

{
  "observers": {
    "subscriberTimeout": 5,
    "maxRetryAttempts": 10,
    "backoffDelay": 1,
    "exponentialBackoffDelayFactor": 2,
    "maximumBackoffDelay": 600,
    "watchdogInterval": 60
  }
}

Property	Type	Default	Description
subscriberTimeout	number	5	Timeout in seconds for observer subscriber calls
maxRetryAttempts	number	10	Maximum retry attempts for failed partitions (0 = infinite)
backoffDelay	number	1	Initial backoff delay in seconds
exponentialBackoffDelayFactor	number	2	Exponential backoff multiplier
maximumBackoffDelay	number	600	Maximum backoff delay in seconds
watchdogInterval	number	60	Interval in seconds between watchdog checks; the watchdog verifies connected clients are still active, running jobs (replay and catch-up) are still progressing, and NextEventSequenceNumber is up-to-date
