Is this a replacement for dynamodb streams? Hard to see the difference other than removing the lambda in between the old process. Thanks in advance.

I would not say it's a replacement. They are slightly different conceptually, although you can achieve similar things with both.

DynamoDB stream allows you to consume Change Data Capture (CDC) events and process them.

EventBridge is an event broker. You can use it to achieve the pub/sub pattern and decouple the event emitter and subscribers.
