I would offer, that depending on your querying needs with a little added complexity, you could replicate the data to an elasticsearch cluster for more complicated queries and use dynamo as the source of record/control.

IIRC, you can setup events based on dynamo records that can trigger a lambda function to update the search db.

This what I do: all writes go to Dynamo and it replicates to ES for querying/filtering. It's the best of both worlds for operational stuff, IMHO, although still not perfect for ad-hoc querying like SQL.

No matter what, all data has to land in a data lake for BI and general reporting.

And always define reporting requirements up front. The last thing you want to find out is that you need a real-time dashboard and you don’t have the services or storage to support it.
