# This test is to detect that SQL statements that violate FK can also be successfully synchronized to the
# downstream MySQL class with FK detection enabled.
# This is because during the synchronization process, CDC may generate some intermediate SQL statements that violate FK.

# we first disable foreign key check in upstream, and create two tables with FK constraints.
# then we insert some data to the tables, and check the data is synchronized to the downstream.
