EventBridge and Lambda different inputs

Question

I need to run a Lambda Function with a Thousand of different inputs, I did it with a Event Bus and another lambda that send the events reading de input from a DynamoDB.

Is that the best way to do this? The lambda that send the events to the event bus, take too much time, and I need to do a loop to send 10 entries at time for the event bus limitations, in boto3.

Answer 1

You can still trigger a stepfunction from Eventbridge and perform a parallel scan with dynamodb to produce the input for the lambda.

Alternatively you can update every dynamodb item with lambda or stepfunction and use dynamodb streams to trigger your lambda.
