TIDB DM功能使用技巧
DM 提供了 Table routing、Block & Allow Table Lists、Binlog event filter 等基本功能，适用于不同的迁移场景。在迁移之前，建议先了解下这些基本功能，根据需求进行选择和配置。
Table routing
Table routing 可以将上游 MySQL/MariaDB 实例的某些表迁移到下游指定表，它也是分库分表合并迁移所需的一个核心功能。
Block & Allow Table Lists
上游数据库实例表的黑白名单过滤规则，可以用来过滤或者只迁移某些 database/table 的所有操作。
Binlog event filter
Binlog event filter 是比迁移表黑白名单更加细粒度的过滤规则，可以指定只迁移或者过滤掉某些
schema / table 的指定类型 binlog，比如 INSERT、TRUNCATE TABLE
1、MySQL同步数据至TiDB集群，常见场景如分库分表的多个MySQL数据库同步数据至TiDB集群
2、TiDB集群同步数据至TIDB集群
