Regarding the FAQ note "How to reduce airflow dag scheduling latency in production" - Per https://github.com/apache/airflow/blame/f097ae39a7243bd25d4d26664bc259981b2ba217/docs/faq.rst#L209: > User should consider to increase ``scheduler_heartbeat_sec`` config to a higher value (e.g 60 secs) which controls how frequent the airflow scheduler gets the heartbeat and updates the job's entry in database. However, since `scheduler_heartbeat_sec` is used as a duration (not as heartbeats/sec rate), increasing it to 60 (from the default 5 sec) would actually cause scheduling to become more sluggish, thus increasing latency. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
