Why would you expect an OLTP db like DDB to work for ETL? You'd have the same problems if you used Postgres.

It's not like AWS is short on ETL technologies to use...

Even in an OlTP db, there is often a need to bulk import and export data. AWS has methods in most supported data stores - ElasticSearch, DDB, MySQL, Aurora, Redshift, etc to bulk insert from S3.
