Query to pipeline

A pipeline is a recurring obligation

A one-off query can be wrong once. A daily pipeline can repeat the same wrong answer for weeks. A reliable pipeline needs four things: idempotence (running the same date twice does not duplicate rows), observability (a run leaves logs and other evidence), recoverability (you can repair an earlier date), and enforceability (checks can stop bad output).

Bruin's table update settings and date ranges support repeatable work. logs/, validation output, checks, and unit tests provide evidence. A separate environment and an incremental key - the field that identifies the date group to replace - keep repairs limited. An agent is a useful collaborator when its mistakes become visible and reviewable.

Your task

Write a short answer in the conversation: classify one risk for each of the four properties and name the repository or Bruin feature that addresses it. Then say review my work.

Check your understanding

• What does idempotent mean here?
• Which mechanism makes a bad metric fail loudly?
• Name the four required properties.

Do it with your agent

Say next lesson, answer the three questions one at a time, then complete the task and say review my work.

Rubric

• Names idempotence, observability, recoverability, and enforceability.
• Gives one distinct failure risk for each property.
• Maps each property to a concrete mechanism such as a table update setting, logs, date-range runs, checks, or tests.
