Processing Millions of Records Through Shopify: Lessons From High-Volume Integrations

Short summary

A practical guide to scaling Shopify integrations from 1,000 to 500,000+ records per day. Key shifts include using the Bulk Operations API instead of paginated GraphQL, implementing dynamic throttle-based pacing, moving webhook processing to async queues with dead letter queues, and enforcing idempotency to handle duplicate delivery. The core insight is that high-volume requires a fundamentally different architecture, not just faster code.

• •Switch from paginated GraphQL to Bulk Operations API for large catalogs
• •Implement dynamic throttling based on throttleStatus instead of hardcoded sleeps
• •Use async queue processing for webhooks and enforce idempotency for duplicate delivery
