Rules that apply · 2

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 a conflict policywarning

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 datastore without a cachewarning

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
