| Bases: :class:`airflow.sensors.base_sensor_operator.BaseSensorOperator` |
| |
| Checks for the existence of a record in a Cassandra cluster. |
| |
| For example, if you want to wait for a record that has values 'v1' and 'v2' for each |
| primary keys 'p1' and 'p2' to be populated in keyspace 'k' and table 't', |
| instantiate it as follows: |
| |
| >>> cassandra_sensor = CassandraRecordSensor(table="k.t", |
| ... keys={"p1": "v1", "p2": "v2"}, |
| ... cassandra_conn_id="cassandra_default", |
| ... task_id="cassandra_sensor") |
