Amazon DynamoDB vs Redis
Two of fourteen models named Amazon DynamoDB first on the direct prompt; zero named Redis. Both were named by all fourteen models and Amazon DynamoDB carries 65 labels and Redis 56, so the shares are not directly comparable.
Named in three categories this edition.
Named in two categories this edition.

The two percentage rows are drawn on one 0 to 100 track, Amazon DynamoDB reading right to left. Rank and label count are printed, not drawn.MongoDB was named alongside these two in fourteen of the fourteen direct answers. MongoDB vs Amazon DynamoDB · MongoDB vs Redis · Amazon DynamoDB vs PostgreSQL
Share is the count of first choices across the direct, paraphrase, budget and scale prompts over all fourteen models, for a mid-market B2B company; rank is within the category; every quote names the model and the prompt it came from. Both figures come from the nosql databases page.
By framing
How many of the fourteen models made each the first choice, per way of asking, and how many argued against it.

Across every category in the November 2026 Edition, Amazon DynamoDB and Redis were named in the same answer 123 times, of the 208 answers naming Amazon DynamoDB and the 152 naming Redis. In those answers Redis took the first choice three times and Amazon DynamoDB fourteen.

Bold names in an answer are the products the judge labeled a first choice; a model naming several gives each of them that label. The full answer text for every row is in the record.

“AI models and experts often advise avoiding DynamoDB as a primary application database unless your use case is a perfect fit for key-value patterns.” Mistral Small · negative prompt · hard negative
“Avoid managed enterprise tiers (DynamoDB, Cosmos DB, etc.)” GLM 4.7 FlashX · budget prompt · hard negative
“DynamoDB (but model your access patterns rigidly upfront)... DynamoDB's provisioned mode can be cheap or catastrophically expensive if misconfigured.” Kimi K2 · scale prompt · soft negative
“lean toward a managed, cloud-specific solution (like DynamoDB or Cosmos DB), even with the potential lock-in” Qwen 3.7 Flash · scale prompt · first choice
