Handle Salesforce API limits and bulk processing at scale
Real World Scenario
Nightly product catalog sync of 800k SKUs exceeds daily API limit and REST composite timeouts.
Expected Answer
• Bulk API 2.0 for large insert/update/delete with job monitoring
• Incremental delta sync using LastModifiedDate indexed queries
• Parallel bulk jobs respecting concurrent job limits per org
• Reduce API calls via composite batching up to 25 subrequests where REST appropriate
• Platform Events or Change Data Capture push instead of poll where possible
• Dedicated integration org or partition windows for heavy jobs
• Salesforce limit increase requests backed by architecture review data
