AWS-IoT 核心代理的最大消息负载大小是多少?

What is the maximum message payload size for a AWS-IoT core broker?

在文档中 AWS Service Limits the payload size limit is not clear for the IoT-Core service. Since we can bridge local mosquitto to AWS IoT, I suppose that this last one should accept the max size of payload from mosquitto witch is 256Mb。那么我可以发送给 AWS-IotCore 中的代理的最大大小(就有效负载而言)是多少?

这个问题的原因是我不想在 mongoDb 中创建很多文档。为此,我将每小时发送一次数据,文档或消息有效负载将比发送几秒钟的数据高得多。

AWS IoT Core 中的最大 MQTT 负载仅为 128kB。

The payload for every publish request is limited to 128 KB. The AWS IoT service rejects publish and connect requests larger than this size.
