Explains ordering guarantees of transports

N-352 · Knowledge knobit · Activity: Design the integration patterns · Competence: Data integration and interoperability

Kafka orders within a partition only; files and HTTP give no order; a resequencer restores order by key.

Can AI do this?

AI does this well Most of the tested AI models master this. 4 of 4 models in the current benchmark master it.

Model	Tier	Probability of mastery	Status
gemini-4-argon	Flagship	97%	Mastered
gemini-3.5-flash-lite	Low cost	94%	Mastered
gpt-6-luna	Low cost	94%	Mastered
claude-haiku-5-5	Low cost	97%	Mastered

Mastered means a probability of at least 90% that the model has this knobit, estimated from its graded answers. “Not shown” means the answers do not settle it either way. How the models are tested.

What it looks like in practice

Expected result: Kafka orders within a partition only; files and HTTP give no order; a resequencer restores order by key.

How it is assessed: Answers a written question on the message ordering correctly
