| Moves data from Hive 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 Hive server. (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 hiveserver2_conn_id: destination hive connection |
| :type hiveserver2_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) |
| :type mysql_preoperator: str |
| :param mysql_postoperator: sql statement to run against mysql after the |
| import, typically used to move data from staging to |
| production and issue cleanup commands. (templated) |
| :type mysql_postoperator: str |
| :param bulk_load: flag to use bulk_load option. This loads mysql directly |
| from a tab-delimited text file using the LOAD DATA LOCAL INFILE command. |
| This option requires an extra connection parameter for the |
| destination MySQL connection: {'local_infile': true}. |
| :type bulk_load: bool |
