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 used as primary store without persistenceerror

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 without eviction policywarning

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 a rebuild patherror

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
