GenericTransfer(sql, destination_table, source_conn_id, destination_conn_id, preoperator=None, *args, **kwargs)[source]¶
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)

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)
