Consistency needs per capability
On This Lesson 4 topics
This lesson is planned. The outline below lists the topics it will cover. The full lesson has not been published yet.
In this lesson
choose availability versus consistency capability by capability.
Planned topics
- Across regions you trade strong consistency against latency and availability (CAP and latency trade-offs).
- Ask the business what a wrong or stale answer costs: a stale product page versus a double-sold item.
- Patterns: single-writer per record, regional ownership of data, eventual consistency with conflict rules.
- Catalog and search tolerate staleness; inventory reservations and payments usually do not.
Draft outline details
Demonstration
a table listing capabilities (catalog, search, cart, checkout, inventory, payments) with tolerated staleness, conflict handling, and a recommended pattern.
Check your understanding
Why not choose one consistency model for the whole platform?
Show answer
Capabilities have different costs of staleness; a single choice over- or under-pays.
