  • schema (str) -- reference to a specific schema in redshift database

  • table (str) -- reference to a specific table in redshift database

  • s3_bucket (str) -- reference to a specific S3 bucket

  • s3_key (str) -- reference to a specific S3 key

  • redshift_conn_id (str) -- reference to a specific redshift database

  • aws_conn_id (str) -- reference to a specific S3 connection If the AWS connection contains 'aws_iam_role' in extras the operator will use AWS STS credentials with a token

  • verify (Optional[Union[bool, str]]) --

    Whether or not to verify SSL certificates for S3 connection. By default SSL certificates are verified. You can provide the following values:

    • False: do not validate SSL certificates. SSL will still be used

      (unless use_ssl is False), but SSL certificates will not be verified.

    • path/to/cert/bundle.pem: A filename of the CA cert bundle to uses.

      You can specify this argument if you want to use a different CA cert bundle than the one used by botocore.

  • column_list (Optional[List[str]]) -- list of column names to load

  • copy_options (Optional[List]) -- reference to a list of COPY options

  • method (str) -- Action to be performed on execution. Available APPEND, UPSERT and REPLACE.

  • upsert_keys (Optional[List[str]]) -- List of fields to use as key on upsert action

execute(self, context)[source]

This is the main method to derive when creating an operator. Context is the same dictionary used as when rendering jinja templates.

Refer to get_template_context for more context.
