IoT Core to Kinesis

Question

I can define action in IoT message rule and push data to Kinesis Data Stream(single shard). Since Kinesis is going to assign sequence number to the messages as they come from Iot Core.
Is there any scalability issue between iot core and Kinesis because of single shard. Example IoT core receives 1000 message and rules redirect all of them to Kinesis. Will kinesis be able to handle? what is the capacity?

Answer

Hi Ozy smile. Please refer to the Kinesis Data Streams quotas and limits: https://docs.aws.amazon.com/streams/latest/dev/service-sizes-and-limits.html

> A single shard can ingest up to 1 MB of data per second (including partition keys) or 1,000 records per second for writes. Similarly, if you scale your stream to 5,000 shards, the stream can ingest up to 5 GB per second or 5 million records per second. If you need more ingest capacity, you can easily scale up the number of shards in the stream using the AWS Management Console or the UpdateShardCount API.
