Query Plan Analysis for production agents

By Michael Samuel Naeem · November 26, 2024 · 6 min read

Query Plan Analysis for production agents means you make agent query plan analysis observable and interruptible — with a named owner, a measurable signal, and a rollback a tired on-call can run. I reach for this when you are replacing a fragile legacy implementation; that is also when shortcuts like one shared path for every tenant and environment start paging people.

This write-up is specific to agent-query-plan-analysis in a agent context, using Postgres, Redis, Temporal for the mechanics while keeping ownership human.

Query Plan Analysis for production agents: production checklist

Agent loops amplify mistakes: one bad tool call can fan out across systems. For agent query plan analysis, that means making failure visible early.

With Postgres, Redis, Temporal, the mechanics are straightforward; the hard part is invariants. The anti-pattern I still see is one shared path for every tenant and environment.

Acceptance check: an on-call engineer can explain system state for agent query plan analysis from one dashboard and one runbook page.

Inputs, outputs, invariants

I treat Query Plan Analysis for production agents as an operations problem first. The goal is to make agent query plan analysis observable and interruptible, not to collect frameworks.

Keep side effects at the edges and make every write idempotent. Query Plan Analysis for production agents without retry semantics is a future incident write-up.

Ship behind a flag, canary by cohort, and write the rollback in the PR description. Query Plan Analysis for production agents that needs a hero is not done.

Concretely, being able to make agent query plan analysis observable and interruptible forces explicit choices: source of truth, timeout budgets, and which errors users see versus operators.
