max_failed_heartbeats:
description: |
The maximum number of consecutive failed heartbeats before terminating
the task instance process.
+
+ Unlike other calls to the execution API, heartbeats are not retried.
This setting and
+ ``min_heartbeat_interval`` together determine how long a worker
tolerates an unreachable API server
+ before killing running tasks.
version_added: 3.0.0
type: integer
example: ~
- default: "3"
+ default: "20"
Review Comment:
