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.

Push fan-out without a celebrity thresholdwarning

push-fanout-without-celebrity-path

Pure push fan-out over a social graph is brutal at the tail: one post from an account with millions of followers becomes millions of cache writes. A follower threshold above which readers merge at read time bounds that write amplification.

— all of these hold:
— the node's `fanoutStrategy` is "push"
— the node's `fanoutThreshold` has no value
— the design contains a node of kind graph-database

Shared worker pool across queueswarning

shared-worker-pool-across-queues

One worker pool consuming several queues lets a slow or poisoned queue starve the others. That is precisely what the design's per-queue isolation requirement forbids.

— all of these hold:
— the node has more than 1 incoming edge from a queue
— the design requirement `isolation.perQueue` is true

Stateful node without zone redundancyerror

stateful-node-without-zone-redundancy

A stateful compute node pinned to exactly one availability zone disappears with that zone, and its state goes with it. Nodes inside a cell are exempt, because there the cell is deliberately single-zone and redundancy comes from the other cells.

— all of these hold:
— the node's `stateless` is false
— the node sits inside exactly 1 availability-zone group
— this does not hold:
— the node sits inside at least one cell group
