# 第二个事件过滤器规则
# [[filter.event-filters]]
# matcher = ["test.fruit"] # 该事件过滤器只应用于 test.fruit 表
# ignore-event = ["drop table", "delete"] # 忽略 drop table 的 DDL 事件和 delete 类型的 DML 事件
# ignore-event = ["drop table", "delete"] # 忽略 drop table 的 DDL 事件和 delete 类型的 DML 事件。需要注意的是，在更新 TiDB 中聚簇索引的列值时，TiCDC 会将一个 UPDATE 事件拆分成为 DELETE 和 INSERT 事件，TiCDC 无法将该类事件识别为 UPDATE 事件，因此无法正确地进行过滤。
# ignore-sql = ["^drop table", "alter table"] # 忽略以 drop table 开头的，或者包含 alter table 的 DDL 语句
# ignore-insert-value-expr = "price > 1000 and origin = 'no where'" # 忽略包含 price > 1000 和 origin = 'no where' 条件的 insert DML
