> Considering the kind of resources Apache Cassandra requires to run
Makes no sense. There is plenty of talent at AWS to run Cassandra proper on AWS for less money than they're currently charging for Dynamo. This was true before this announcement - it's how people like Instaclustr stay in business (containerized cassandra as a service on EC2).
The new Amazon Managed Apache Cassandra Service does use the open source Apache Cassandra code. The team is excited about working with the development community on Cassandra. See more at https://aws.amazon.com/blogs/opensource/contributing-cassand...
Can we access the sstables of our tables?
Can we do triggers and UDF?
Can we access the timestamps at a CELL LEVEL like cassandra proper (VERY important for online/downtimeless data migration)
However, I think the real reason is not even that. I suspect underneath it uses modified version of DynamoDB and it's just wire compatible with Cassandra. That's how they are offering pay as you go pricing and auto-scaling.
Considering the kind of resources Apache Cassandra requires to run, I don't think they can offer this kind of pricing. This is the same company that charges $0.2 per hour to run a K8s cluster.
