VladaZakharova opened a new pull request, #76821:
URL: https://github.com/apache/airflow/pull/76821
Partitions filled by streaming exist as soon as the first row arrives, so
BigQueryTablePartitionExistenceSensor lets batch tasks read them while rows are
still coming in, and fixed delays add latency without guaranteeing completeness.
New BigQueryTablePartitionReadySensor waits until a partition has rows and
has received no new rows for a settle period. New
PubSubSubscriptionDeliveredSensor waits until every message published before a
given time has been acknowledged, so pipelines fed from PubSub can wait for the
backlog to be delivered first. Both support deferrable mode.
