Shopify Performance Tuning

Overview

Optimize Shopify API performance through GraphQL query cost reduction, bulk operations for large data exports, response caching, and Storefront API for high-traffic public-facing queries.

Prerequisites

• Understanding of Shopify's calculated query cost system
• Access to the Shopify-GraphQL-Cost-Debug: 1 header for cost analysis
• Redis or in-memory cache available (optional)

Instructions

Step 1: Analyze and Reduce Query Cost

Use the debug header to inspect requestedQueryCost vs actualQueryCost. Reduce cost by selecting only needed fields and lowering first: page sizes (250 to 50 can cut cost by 5x).

See Query Cost Optimization for debug commands and before/after examples.
