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

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:

复制代码

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：

html 复制代码

source:
  type: mysql
  hostname: xxx
  port: 3306
  username: root
  password: xxx
  tables: adb.\.*,bdb.\.*
  server-id: 6410-6490
  server-time-zone: Asia/Shanghai
  scan.startup.mode: latest-offset

sink:
  type: doris
  fenodes: xxx:8130,xxx:8130,xxx:8130
  username: root
  password: xxx
  table.create.properties.light_schema_change: true

route:
  - source-table: adb.\.*
    sink-table: test_sync.adb_db_<>
    replace-symbol: <>

pipeline:
  name: test_sync
  parallelism: 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
