Bases:airflow.sensors.base_sensor_operator.BaseSensorOperator

Waits for a partition to show up in Hive.

Note: Because partition supports general logical operators, it can be inefficient. Consider using NamedHivePartitionSensor instead if you don’t need the full flexibility of HivePartitionSensor.

Parameters

  • table (str) – The name of the table to wait for, supports the dot notation (my_database.my_table)

  • partition (str) – The partition clause to wait for. This is passed as is to the metastore Thrift client get_partitions_by_filter method, and apparently supports SQL like notation as in ds='2015-01-01' AND type='value' and comparison operators as in "ds>=2015-01-01"

  • metastore_conn_id (str) – reference to the metastore thrift service connection id
