class airflow.operators.generic_transfer.GenericTransfer(sql, destination_table, source_conn_id, destination_conn_id, preoperator=None, *args, **kwargs)[source]

Bases: airflow.models.BaseOperator

Moves data from a connection to another, assuming that they both provide the required methods in their respective hooks. The source hook needs to expose a get_records method, and the destination a insert_rows method.

This is meant to be used on small-ish datasets that fit in memory.

  • sql (str) – SQL query to execute against the source database. (templated)

  • destination_table (str) – target table. (templated)

  • source_conn_id (str) – source connection

  • destination_conn_id (str) – source connection

  • preoperator (str or list[str]) – sql statement or list of statements to be executed prior to loading the data. (templated)
