新增优点：Pattern Replacement in routing rules
flinkcdc 3.2.0版本相较于3.1.0版本，避免了多表多sink多次写 route 路由的麻烦，类似于统一前后缀的形式多表多sink，通过<>正则，大大减少了书写
官网：
Route | Apache Flink CDC
Pattern Replacement in routing rules #
If you’d like to route source tables and rename them to sink tables with specific patterns, replace-symbol could be used to resemble source table names like this:
route:- source-table: source_db.\.*sink-table: sink_db.<>replace-symbol: <>description: route all tables in source_db to sink_db
Then, all tables including source_db.XXX will be routed to sink_db.XXX without hassle.
包括source_db.XXX在内的所有表都将毫无麻烦地路由到sink_db.XXX
应用：
flinkcdc版本升级 mysql to doris 在 lib 下添加依赖jar包：
source:type: mysqlhostname: xxxport: 3306username: rootpassword: xxxtables: adb.\.*,bdb.\.*server-id: 6410-6490server-time-zone: Asia/Shanghaiscan.startup.mode: latest-offsetsink:type: dorisfenodes: xxx:8130,xxx:8130,xxx:8130username: rootpassword: xxxtable.create.properties.light_schema_change: trueroute:- source-table: adb.\.*sink-table: test_sync.adb_db_<>replace-symbol: <>pipeline:name: test_syncparallelism: 1
adb会根据route路由规则进行整库同步，bdb则会根据默认的无路由规则进行整库同步。
flinkcdc pipeline 数据库仍然需要在起任务前提前创建好，表则会在source初始阶段自动创建，表注释仍然不生效
