Rules that apply · 3

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.

cache-as-primary-store-without-persistence

This cache is the only copy of its data and has persistence turned off. A restart loses the data outright.

  • — all of these hold:
  • — the node's `usedAsPrimaryStore` is true
  • — the node's `persistence` is false
cache-missing-eviction-policy

A cache with no declared eviction policy inherits whatever the vendor chose, and most vendors default to evicting nothing. The cache fills up and then starts refusing writes.

  • — any of these hold:
  • — the node's `evictionPolicy` has no value
  • — the node's `evictionPolicy` is "none"
materialised-cache-without-rebuild-path

A cache holding materialised views has to be rebuildable from a durable store or a worker. With nothing feeding it, a cold cache is a permanent gap rather than a slow start.

  • — all of these hold:
  • — the node's `materialised` is true
  • — this does not hold:
  • — the node has at least one incoming edge from a sql-database, nosql-database, worker or stream

# evictionPolicy is deliberately not defaulted: Redis ships with noeviction, which is the
# behaviour the cache-missing-eviction-policy rule exists to surface.
