## About

# Event Streaming Platform Design

## When to use

Use for Kafka, Pulsar, Event Hubs or similar streaming platform foundations.

## Objective

Produce a practical, concise, traceable architecture artefact that a coding agent can use to guide implementation or review.

## Procedure

1. Define workloads and tenants.
2. Define naming and environments.
3. Define topic/stream lifecycle.
4. Define partitioning and retention.
5. Define schema registry policy.
6. Define access controls and quotas.
7. Define observability and support model.
8. Define deprecation process.

## Required outputs

- Platform model
- Topic strategy
- Partition/retention policy
- Schema/access policy
- Quotas
- Support model

## Best-practice alignment

Apply event-driven best practice: business event semantics, producer/consumer ownership, schema contracts, compatibility, ordering, partitioning, idempotency, replay, retention, lineage, observability and operational SLOs. Prefer **CloudEvents** for interoperable envelopes and **AsyncAPI** (or registry-backed schemas) for channel and message contracts on the platform.

## Quality checks

- Topics have owners.
- Partition strategy is explicit.
- Retention supports replay/compliance.
- Access is least privilege.

## Avoid

Do not allow unowned shared topics.

## Decision template

For each topic family, define naming convention, environment strategy, tenant, owner, partition key, retention, replay expectation, schema subject, access policy, quota, support tier and deprecation route. Reject unowned shared topics because they become hidden integration contracts with unclear cost, lineage and incident accountability.
