### Multi-leader store without a conflict policy `multi-leader-store-without-conflict-policy` (warning)

- Page: https://localhost:3000/catalogue/rules/multi-leader-store-without-conflict-policy.md
- Why: 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.
- Applies to: every node of kind nosql-database
- Message: Store '{{node.id}}' is multi-leader across regions with no conflict resolution policy. Declare last-writer-wins, vector-clock or app-merge.

It fires when:

- 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 cache `read-heavy-path-without-cache` (warning)

- Page: https://localhost:3000/catalogue/rules/read-heavy-path-without-cache.md
- Why: 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.
- Applies to: every node of kind sql-database or nosql-database
- Message: Datastore '{{node.id}}' serves a read-heavy workload directly from application servers and the design has no cache.

It fires when:

- 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
