Refer to task templates and tutorial
While this configuration is similar to that of snapshot migration, the only differences are:
[extractor]
extract_type=check_log
check_log_dir=./dt-tests/tests/mysql_to_mysql/revise/basic_test/check_log
- For [router], refer to config details.
- Refer to task_config.ini in tests:
- dt-tests/tests/mysql_to_mysql/revise
- dt-tests/tests/pg_to_pg/revise
