Dsql

If you're building on Aurora DSQL, this skill handles the full stack: schema design, query execution via MCP tools, migrations from MySQL or PostgreSQL, ORM adapters for Django/Hibernate/Rails, and bulk loading with aurora-dsql-loader. It knows the sharp edges, like unsupported foreign keys (you get code generation for app-layer validation instead), optimistic concurrency retry patterns, and the table recreation dance needed for DROP COLUMN or ALTER TYPE. The reference library is thorough, covering IAM auth, multi-tenant patterns, collation quirks, and what to do when GIN indexes or ENUMs don't translate cleanly. Useful if you're migrating existing schemas or need to understand why DSQL says no to certain DDL operations.
