.. py:class:: MetastorePartitionSensor(*, table, partition_name, schema = 'default', mysql_conn_id = 'metastore_mysql', **kwargs)

   Bases: :py:obj:`airflow.sensors.sql.SqlSensor`

   An alternative to the HivePartitionSensor that talk directly to the
   MySQL db. This was created as a result of observing sub optimal
   queries generated by the Metastore thrift service when hitting
   subpartitioned tables. The Thrift service's queries were written in a
   way that wouldn't leverage the indexes.

   :param schema: the schema
   :param table: the table
   :param partition_name: the partition name, as defined in the PARTITIONS
       table of the Metastore. Order of the fields does matter.
       Examples: ``ds=2016-01-01`` or
       ``ds=2016-01-01/sub=foo`` for a sub partitioned table
   :param mysql_conn_id: a reference to the MySQL conn_id for the metastore

   .. py:method:: poke(self, context)

      Function that the sensors defined while deriving this class should
      override.
