Certification Lanes

Lane B — Database Connectors

Native database drivers. Full CDC support. Deep integration with real database instances.

  • Native driver (pg, mysql2, mongodb, etc.)
  • Real CDC implementation (log-based, streams, polling)
  • Docker integration testing
  • Schema discovery, full extraction, incremental extraction
19 connectors • 17 with 100% pass rate

Lane A — SaaS Connectors

REST API connectors. Real endpoints, real schemas. Uses SaaSConnector base for auth, pagination, rate limiting.

  • Real API endpoint (Stripe, Salesforce, HubSpot, etc.)
  • Schema defined with real field names
  • Auth + pagination + rate limiting handled
  • CDC polling with watermarks
301 connectors • 25 with 100% pass rate

How they work: All Lane A connectors extend the SaaSConnector base class, which handles authentication (bearer, OAuth2, API key), pagination (cursor, offset, link), rate limiting, and CDC polling with watermarks. Each connector defines its own API endpoints and schemas.
