The sequence tells a story.
Identity, order and recovery
make that story useful.

WHAT TRAVELS WITH AN EVENT?

A fact.
A context.
A way back.

01

A shared event envelope

Make identity, type, source and occurrence time explicit. Separate event metadata from the domain payload and version both deliberately.

02

Ordering where it matters

Choose a stream or partition key based on the business entity. Global ordering is rarely the same requirement as consistent updates to one record.

03

Recoverable consumers

Store progress after applying a safe unit of work. Plan for redelivery and make the resulting business action idempotent.

04

Retention with a purpose

Set a replay window from recovery and analysis needs. Storage limits, sensitive fields and schema compatibility belong in the same decision.

Design an event as a fact

A stable envelope helps producers and consumers evolve separately.

Ordering and partition boundaries

Choose the smallest ordering guarantee the domain requires.

Consumer recovery and replay

A replay should be controlled, inspectable and safe.
