Discuss Salesforce Plat-Dev-301 Exam Topic 3 Question 5

Millions of Accounts are updated every quarter from an external system. What is the optimal way to update these in Salesforce?

AComposite REST API

BSOAP API

CBulk API

DApex REST Web Service

Suggested Answer: C

Comprehensive and Detailed

When dealing with Large Data Volumes (LDV)---specifically in the range of hundreds of thousands to millions of records---the Bulk API (Option C) is the only optimal choice.

The Bulk API is based on REST principles but is optimized for processing large sets of data asynchronously. Instead of processing records one by one or in small synchronous chunks (which would hit time limits and consume many API calls), the Bulk API allows you to upload a CSV file or JSON batch. Salesforce then processes these records in the background using parallel processing.

Options A and B (REST/SOAP) are designed for real-time, synchronous interactions with a limited number of records and would hit rate limits or timeout for millions of records. Option D is for custom logic and is subject to the same synchronous execution limits as standard REST.

But A) Composite REST API could work too for smaller batches. Just depends on the use case.

I think C) Bulk API is the best choice. It handles large data volumes efficiently.

Apex REST Web Service is too complex for this, stick with Bulk API!

I’m surprised Bulk API is the top choice, I thought SOAP was more reliable.

Wait, isn't the Composite REST API better for smaller batches?

Totally agree, Bulk API handles millions of records efficiently!

I think the Bulk API is the way to go for large updates.

I’m a bit confused; I thought SOAP API was more for real-time updates, but does it really fit for this scenario?

Casie 3 months ago

I practiced a similar question where Bulk API was highlighted for handling large volumes, so I’m leaning towards that option.

I think the Composite REST API could be useful too, but I’m not confident it handles millions of records as efficiently as the Bulk API.

I remember we discussed the Bulk API being the best choice for large data updates, but I'm not entirely sure if it’s the only option.
