/**
 * @file test_ignore_min_gtid-t.cpp
 * @brief This test file verifies the functionality of the mysql-ignore_min_gtid_annotations variable.
 *  - Sets mysql-ignore_min_gtid_annotations=true, so queries annotated with min_gtid succeed.
 *  - Sets mysql-ignore_min_gtid_annotations=false, so queries annotated with min_gtid fail.
