Parameters

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

  • expression (str) – The partition clause to wait for. This is passed as is to the AWS Glue Catalog API’s get_partitions function, and supports SQL like notation as in ds='2015-01-01' AND type='value' and comparison operators as in "ds>=2015-01-01". See https://docs.aws.amazon.com/glue/latest/dg/aws-glue-api-catalog-partitions.html #aws-glue-api-catalog-partitions-GetPartitions

  • database_name (str) – The name of the catalog database where the partitions reside.

  • poke_interval (int) – Time in seconds that the job should wait in between each tries

  • deferrable (bool) – If true, then the sensor will wait asynchronously for the partition to show up in the AWS Glue Catalog. (default: False, but can be overridden in config file by setting default_deferrable to True)

  • aws_conn_id – The Airflow connection used for AWS credentials. If this is None or empty then the default boto3 behaviour is used. If running Airflow in a distributed manner and aws_conn_id is None or empty, then default boto3 configuration would be used (and must be maintained on each worker node).

  • region_name – AWS region_name. If not specified then the default boto3 behaviour is used.

  • verify – Whether or not to verify SSL certificates. See: https://boto3.amazonaws.com/v1/documentation/api/latest/reference/core/session.html

  • botocore_config – Configuration dictionary (key-values) for botocore client. See: https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html
