   Bases: :py:obj:`airflow.providers.common.sql.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 would not 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
