DynamoDB 10 years later
We're at early stages of planning an architecture where we offload pre-rendered JSON views of PostgreSQL onto a key value store optimised for read only high volume. Considering DynamoDB, S3, Elastic, etc. (We'll probably start without the pre-render bit, or store it in PostgreSQL until it becomes a problem).When looking at DynamoDB I noticed that there was a surprising amount of discussion around the requirement for provisioning, considering node read/write ratios, data characteristics, etc. Basically, worrying about all the stuff you'd have to worry about with a traditional database.To be honest, I'd hoped that it could be a bit more 'magic', like S3, and it AWS would take care of provisioning, scaling, sharding etc. But it seemed disappointingly that you'd have to focus on proactively worrying about operations and provisioning.Is that sense correct? Is the dream of a self-managing, fire-and-forget key value database completely naive?
