notes
from the
field.

every unique label combination is its own series in prometheus, and one label holding an id or a raw path can outweigh every other metric combined.

terraform's moved, import, and removed blocks turn state surgery into configuration changes that get a plan, a review, and a history like any other.

kargo models the sequence and requirements for promoting a version between environments, layering on top of argocd without replacing its sync.

rolling updates drop connections when kubelet sends sigterm before the endpoint is removed from routing. the fix spans the pod spec and the application.

nats routes messages by subject with a single small binary, and its jetstream layer adds persistence, replay, and at-least-once delivery on top.
