Sequin's first launch week introduced several new features and improvements aimed at enhancing data integration capabilities and developer experience. Stripe has become generally available as a new source, with a re-architected sync to address eventual consistency and support SQL Writes, allowing updates to customer subscriptions. GitHub was added as the fifth source, enabling read and write operations on repositories, pull requests, and issues, while cautioning against discrepancies in GitHub's API. Developer experience enhancements include schema downloads directly from the Sequin console and asynchronous migrations to prevent sync failures. Partnerships with app building platforms like Glide, Retool, and Superblocks were established to simplify app development, and a new feature, Sequin Events, allows users to subscribe to events from data sources via Kafka and webhooks. These developments mark the beginning of Sequin's efforts to create efficient, turnkey infrastructure for data integrations and app development.
