Data Brain

Structured data as a service -- the database equivalent of Storage Brain. Data Brain wraps the full DatabaseAdapter interface (43 methods) in an HTTP API backed by Cloudflare D1, with a TypeScript SDK for client-side use.

Features

• Full DatabaseAdapter Coverage -- 43 methods exposed over HTTP (tables, columns, rows, views, relations, select options, file references)
• Multi-Tenant -- API key isolation with per-tenant quota and workspace scoping
• Cloudflare D1 Backend -- Edge-first, SQLite-based storage with minimal latency
• TypeScript SDK -- Full type safety with automatic retry and typed errors
• Drop-In Adapter -- Use as a DatabaseAdapter for @marlinjai/data-table-react

Architecture

Data Brain uses a three-layer design:

1. SDK -- TypeScript client with retry logic, typed errors, and full method coverage
2. API -- Hono-based Cloudflare Worker with auth, ownership verification, and Zod validation
3. Storage -- Cloudflare D1 via @marlinjai/data-table-adapter-d1
