## Rules that apply · 3

### Push fan-out without a celebrity threshold `push-fanout-without-celebrity-path` (warning)

- Page: https://localhost:3000/catalogue/rules/push-fanout-without-celebrity-path.md
- Why: 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.
- Applies to: every node of kind worker
- Message: Worker '{{node.id}}' pushes fan-out over a social graph with no fanoutThreshold. Declare a follower threshold above which timelines are merged at read time.

It fires when:

- 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 queues `shared-worker-pool-across-queues` (warning)

- Page: https://localhost:3000/catalogue/rules/shared-worker-pool-across-queues.md
- Why: 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.
- Applies to: every node of kind worker
- Message: Worker '{{node.id}}' consumes more than one queue while the design requires per-queue isolation. Give each queue its own worker pool.

It fires when:

- 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 redundancy `stateful-node-without-zone-redundancy` (error)

- Page: https://localhost:3000/catalogue/rules/stateful-node-without-zone-redundancy.md
- Why: 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.
- Applies to: every node in category compute
- Message: Stateful node '{{node.id}}' lives in exactly one availability zone. A zone outage takes its state with it.

It fires when:

- 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
