RedshiftSQLTrigger

Base class for all triggers.
class amazon.aws.triggers.redshift_sql.RedshiftSQLTrigger(task_id, polling_period_seconds, aws_conn_id, query_ids)

Bases: airflow.triggers.base.BaseTrigger

Base class for all triggers.

A trigger has two contexts it can exist in:

  • Inside an Operator, when it’s passed to TaskDeferred

  • Actively running in a trigger worker

We use the same class for both situations, and rely on all Trigger classes to be able to return the (Airflow-JSON-encodable) arguments that will let them be re-instantiated elsewhere.

serialize(self)

Serializes RedshiftSQLTrigger arguments and classpath.

async run(self)

Make async connection and execute query using the Amazon Redshift Data API.
