es sync之 adapter 使用

Adapter 分为两部分，一个是启动器，一个是适配器，启动器为 Springboot 项目，适配器以 fat jar 的形式将自己所需的依赖打成一个包， 以SPI的方式让启动器动态加载

启动器

连接 CANAL

如果 CANAL 是单例模式，则配置

canalServerHost: 127.0.0.1:11111

HA 模式

zookeeperHosts: 120.78.200.102:2181,120.78.200.102:2182,120.78.200.102:2183

TCP

canal.conf.mode: tcp

KAFKA 及 RabbitMQ

mqServers: 120.78.200.102:9092 # 这里需要配置单机地址

数据源

srcDataSources:
  zyloopsDS:
    url: jdbc:mysql://120.78.200.102:3306/x1?useUnicode=true
    username: root
    password: 123456

适配器

canalAdapters:
  - instance: zyloops # canal instance Name or mq topic name
  # - topic: zyloops
    groups:
      - groupId: g1
        outerAdapters:
          - name: logger
          - name: es
            hosts: 192.168.71.246:9300
            properties:
              cluster.name: ebuy-cloud-cluster
              searchguard.ssl.transport:
                pemkey_filepath: D:\projects\canal\client-adapter\launcher\target\canal-adapter\conf\ssl\spock.key
                pemcert_filepath: D:\projects\canal\client-adapter\launcher\target\canal-adapter\conf\ssl\spock.pem
                pemtrustedcas_filepath: D:\projects\canal\client-adapter\launcher\target\canal-adapter\conf\ssl\root-ca.pem
                pemkey_password: 3QgfFoYd8Ken

 instance 与 canal 实例名称对应

groupId 为分组 ID，组间适配器并行，组内串行，避免使用组内适配器

-name 指定适配器类型，此配置中加载 logger，es 适配器

hosts 为 ES 地址及端口

properties 为 特定配置，此处为连接 ES 的相关配置

ES 适配器

dataSourceKey: zyloopsDS
destination: zyloops
groupId: g1
esMapping:
  _index: zyloops_user
  _type: _doc
  _id: _id
  upsert: true
  sql: "select a.id as _id, a.name as _name, a.age as _age, b.name as _clzName, c.score as _score from t_user a left join t_clz b on a.id = b.user_id left join t_score c on a.id = c.user_id"
