| Moves data from Presto to MySQL, note that for now the data is loaded |
| into memory before being pushed to MySQL, so this operator should |
| be used for smallish amount of data. |
| |
| :param sql: SQL query to execute against Presto. (templated) |
| :type sql: str |
| :param mysql_table: target MySQL table, use dot notation to target a |
| specific database. (templated) |
| :type mysql_table: str |
| :param mysql_conn_id: source mysql connection |
| :type mysql_conn_id: str |
| :param presto_conn_id: source presto connection |
| :type presto_conn_id: str |
| :param mysql_preoperator: sql statement to run against mysql prior to |
| import, typically use to truncate of delete in place |
| of the data coming in, allowing the task to be idempotent (running |
| the task twice won't double load data). (templated) |
