Correct. Lambda isn't designed for high data through put. That's what Amazon Kinesis is for. Each Kinesis shard can handle 1000KB/s data injestion rates. You would write your data to a kinesis stream, then use Lambda to respond to the kinesis event to write data to your DynamoDB table.
Thanks for the info on this, I hadn't seen Kinesis before. I also tried something similar with S3 upload but Kinesis looks a much better solution for what I'm trying to do.
Kinesis isn't a good idea for low-latency queueing. It can handle high throughput, but it can often take anywhere from one to ten seconds for a message to make it through the queue.
Given that DynamoDB can reliably write in the 4-5ms range, a kinesis queue may not be necessary. Unless the point of the Kinesis layer is to keep the cost of DynamoDB provisioning low?
