arroyo 对于kafka 有着很不错的集成支持（目前版本可以说是优先支持的），使用原生kafka 是一个选择，但是部署以及管理感觉比较费事
以前简单介绍过redpanda，所以尝试下集成

环境准备

• docker-compose
  包含了redpandadata console，connect，以及一个测试，对于arroyo 使用了与redpandadata 同一个网络

启动&测试

• 启动

docker-compose up -d

• 创建kafka topic

• 配置arroyo connections、source 以及sink
  我们测试的时候因为部署了一个owl-shop 服务，可以直接将owl-shop 的topic 作为source，然后写入到demo topic中（sink）
  connections 配置

kafka source 配置

json schema 定义

{

"$schema": "http://json-schema.org/draft-04/schema#",

"title": "Product",

"type": "object",

"properties": {

"version": { "type": "number" },

"id": { "type": "string" },

"customer": {

"type": "object",

"properties": { "id": { "type": "string" }, "type": { "type": "string" } }

},

"type": { "type": "string" },

"firstName": { "type": "string" },

"lastName": { "type": "string" },

"state": { "type": "string" },

"street": { "type": "string" },

"houseNumber": { "type": "string" },

"city": { "type": "string" },

"zip": { "type": "string" },

"latitude": { "type": "number" },

"longitude": { "type": "number" },

"phone": { "type": "string" },

"additionalAddressInfo": { "type": "string" },

"createdAt": { "type": "string" },

"revision": { "type": "number" }

}

}

kafka sink 创建

• 创建job （pipeline）

sql 查询

job 执行

redpanda console 效果

说明

arroyo+redpanda 的pipeline 还是一种不错的选择，至少redpanda 部署以及使用还是比较简单的，而且支持不少kafaka 周边的兼容，是一个不错的选择，
arroyo 测试目前来说支持的source 以及sink 不是很多（核心还是kafaka）但是基于sql 的处理模式真的很方便，相比kafaka 的stream 简单不少，值得尝试下
