group.id：具有相同
group id
的
worker
属于同一个
Connect
集群。集群的连接器和它们
的任务可以运行在任意一个
worker
上。
•
key.converter 和 value.converter：
Connect
可以处理存储在
Kafka
里的不同格式的
数据。这两个参数分别指定了消息的键和值所使用的转换器。默认使用
Kafka
提供的
JSONConverter
，当然也可以配置成
Confluent Schema Registry
提供的
AvroConverter
。
有些转换器还包含了特定的配置参数。例如，通过将
key.converter.schema.enable 设置成
true 或者 false 来指定
JSON
消息是否可以包含
schema
。值转换器也有类似的配置，不过
它的参数名是 value.converter.schema.enable。
Avro
消息也包含了
schema
，不过需要通
过 key.converter.schema.registry.url 和 value.converter.schema.registry.url 来指定
Schema Registry
的位置。
我们一般通过
Connect
的
REST API
来配置和监控 rest.host.name 和 rest.port 连接器。
你可以为
REST API
指定特定的端口。
在启动
worker
集群之后，可以通过
REST API
来验证它们是否运行正常。
