Every rule whose selector covers this component's kind or its category. Whether a rule fires depends on the design: its properties, its edges and its groups.
multi-leader-store-without-conflict-policy
Multi-leader replication accepts concurrent writes in several regions. With no conflict resolution policy declared, divergent replicas are reconciled by accident rather than by design.
- — all of these hold:
- — the node's `replication` is "multi-region-multi-leader"
- — any of these hold:
- — the node's `conflictResolution` has no value
- — the node's `conflictResolution` is "none"
read-heavy-path-without-cache
The design states a read-heavy workload and application servers read this datastore directly, yet the design has no cache anywhere. Every read pays a database round trip.
- — all of these hold:
- — the design requirement `traffic.readWriteRatio` is a number greater than 10
- — the node has at least one synchronous incoming edge from an app-server
- — this does not hold:
- — the design contains a node of kind cache
