Amazon web services 天鹅座和NGSI DynamoDB接收器集成问题

我已经在一个月内完成了教程的学习

吉特回购：

我能够将数据从Cygnus持久化到MongoDB、PostgreSQL数据库和MySQL数据库。我需要将数据从天鹅座保存到DynamoDB。有谁能帮我为Orion Context Broker、Cygnus（Common和NGSI）和NGSI DynamoDB Sink提供正确的docker配置，以及一个示例上下文数据格式和相应的订阅POST请求格式？这样我就可以看到自动创建的DynamoDB表，并且在部署docker映像并将上下文数据发布到代理之后，上下文数据更改会反映在DynamoDB表中
