| Nodes calculate a cluster stress level as a weighted average (with nodes that are more stressed getting more weight). | ||
| If an individual node is stressed, it can enter stress relief individually. | ||
| This may happen, for example, when a single giant trace is concentrated on one node. | ||
| If the cluster as a whole is being stressed by a general burst in traffic, the entire cluster should now enter or leave stress relief at approximately the same time. |

Does this mean that you could expect to see a rise in cross-node network traffic, or do we expect it to be marginal?

You might see the impact of pubsub traffic to and from redis, but it's pretty small; we mostly only publish new values when they're different.
