Agent systems: feature store online offline
Agent systems: feature store online offline means you keep agent side effects idempotent around feature store online offline — with a named owner, a measurable signal, and a rollback a tired on-call can run. I reach for this when on-call already feels weekly pain here; that is also when shortcuts like treating agent feature store online offline as a pure library problem start paging people.
This write-up is specific to agent-feature-store-online-offline in a agent context, using Temporal, OpenTelemetry, Postgres for the mechanics while keeping ownership human.
