Pattern ranking
Paste into your repo's /docs/adr folder or a wiki page.
Set your workload parameters. A rule engine scores eight architecture patterns, explains every point it awards, and assembles a stack for your platform. Tap any for an explanation.
Each control on the left records one fact about your workload. Every pattern starts at 0 points.
About 45 rules each pair a condition, such as volume above 1 TB/day, with point adjustments per pattern. When the condition is true, the rule fires and its points are added.
Some rules are hard constraints. A veto removes a pattern whatever its score; single-node is vetoed above 1 TB/day or at seconds-level freshness.
The highest-scoring core pattern that was not vetoed is recommended. Data Mesh and CDC are overlays and are suggested alongside it once they reach 20 points.
Layers are added only when your parameters need them, then filled from the catalog for your platform. The platform choice never changes pattern scores.
