The playground

Build any DynamoDB operation as a form or raw JSON and run it on the live engine, against a seeded MusicLibrary table. Read the response, the cost (Count, ScannedCount and ConsumedCapacity) and the latency of each call.

MusicLibrary: pk (pk), sk (sk) · 2 secondary indexes

Worked examples: An artist's catalogue · Every artist's profile · A genre, across artists · The same answer, by scan.
