An underrated part of DynamoDB are its streams. You can subscribe to changes and reliably process those in a distributed way. If you're comfortable with the terms "at-least once delivery" and "eventual consistency", you can build some truly amazing systems by letting events propagate reactively through your system, never touching a data store or messaging broker other than DynamoDB itself.

It's not for everyone, but when you get a team up and running with it, it can be shockingly powerful.

Yeah we make use of streams at my work. Really useful. You can hook up streams to a Lambda and have it process events and flow them downstream to a Data Lake or Data Warehouse for analytic workloads. What works really well is pushing data to an S3 bucket with object versioning and replication enabled.

I think dynamoDB streams and kinesis streams work similar under the hood? But dynamoDB streams are way cheaper, pricing is on-demand compared to hourly for Kinesis.
