DynamoDb can integrate with kinesis out of box. It’s a new feature in this year. IMHO, it’s better.The DynamoDb stream has a quota limitation. Per table only can have two steams.

Before it, we have to hook a lambda to publish it to a kinesis, so our data team and backend can consume it in both

For the light events, there is another pro is the schema compatibility. It’s kinda often the publisher will update the new event payload, adding new fields or add new enum items, etc. or remove fields. The light one have less fields and less chance to remove fields.

That’s nice

But when 🙂 they can support find the root cause within nested stack. Previously we have to scroll down many pages and jump to 5 depth nested stack to find the root cause.

Many developers gave us in the first page and throw the issue to infra or platform team to find it

SAM application for lambda?
What a cave age. Why we are still using YAML? AWS have a better one, CDK! Why can we just support it CDK at the first place.

Configure a lambda to consume a SNS topic with FIFO SQS + a DLQ those standard pattern in CFN template is a huge pain!
