Clearly you know nothing about DynamoDB. Durability and consistency are some of its most important features. Item writes to DDB are 100% linearizable. DDB is an extremely well executed CP distributed system, that has had excellent availability over the years.
I used to work on the DynamoDB team. There was a lot of stuff at Amazon that I wasn’t happy about, but the DynamoDB implementation and operation was solid.
? Has durability been a problem for them?
