Modeling a Creator SaaS in a Single DynamoDB Table

Short summary

Truss, a creator SaaS on Vercel, models all entities in a single DynamoDB table using composite keys (CREATOR#userId + SK prefixes). This design eliminates joins and N+1 queries for partition-scoped reads, avoids serverless connection overhead, and scales on-demand from zero cost. Trade-offs include hot partition risk and loss of ad-hoc querying, requiring disciplined upfront access-pattern modeling.
