alt Hacker NewsEverywhere I've worked that uses DynamoDB, someone will invariably write a bunch of abstraction functions that become very annoying to debug, to add functionality, and can break an entire app if changed.
DynamoDB is admittedly very verbose, but it's almost always worth it to keep your CRUD operations written within the SDK rather than as an abstraction.
A better abstraction would be a better SDK then.
BTW repetitiveness is not free, it's cognitive load that a developer must deal with. An abstraction is also a bit of cognitive load that grows with the abstraction's complexity; the point is to find a balance that minimizes it.
