Metaobjects at scale: when content modeling becomes a system
Metaobjects are a database you design once and query for years. The query surface is narrower than the modeling surface, and that is the thing to design around.
Rate-limited, retried and idempotent: integration fundamentals

The Admin GraphQL API: pagination, cost and bulk operations
Most Shopify integrations are throttled because they ask for too much per query, then retry harder. Read the cost object and the problem goes away.
