How to keep high-volume B2C Commerce catalog data and jobs within platform standards and quotas, when a Salesforce big object fits large historical data, and how the Data 360 Ingestion API bulk and streaming patterns differ in format, limits and latency.

- Certification: Salesforce B2C Solution Architect
- Exam section: Data Models and Management
- Study guide: https://www.certifyforce.com/study-guide/b2c-solution-architect

**Official exam objective:**

> Given a scenario, identify appropriate systems of record and describe how you would extend the standard data model for high volume processing, articulate system limitations, and recommend preferred methods for integration between various data formats.

## What the exam expects

- Shrink high-volume B2C Commerce product data (site and locale overrides, orphans, Set and Enum attributes) and explain where the clean-up runs.
- Apply the B2C Commerce job and storefront standards for feeds, transactions, memory, recovery, live calls and job load.
- Decide when a custom big object fits large historical data in the service org and state its limits.
- Choose between the Data 360 Ingestion API bulk and streaming patterns from file format, size, volume and latency.

Key terms: **custom attribute row** (each site-specific or localized value of a B2C Commerce attribute, stored as its own database row); **job load factor** (daily job execution seconds divided by 86,400); **quota** (a monitored B2C Commerce resource limit that logs, warns or errors); **big object** (a Salesforce object on a horizontally scalable, non-transactional store for billions of records); **Ingestion API** (the Data 360 REST interface with bulk and streaming patterns).
