Message queues have been widely used in networked systems for their ability to offload long-running tasks from critical paths, ensuring reliability through guaranteed delivery, persistence, and dead letter queues. However, building a system with message queues requires much more than just the queue itself, including chaining, concurrency, back-off, debouncing, state persistence, prioritization, error handling, idempotency, cancellation, observability, and recovery tooling. Durable execution is now considered the right abstraction for building modern systems, combining durability and flow control to provide reliability and guarantees to application workflows. Developers should consider using durable execution instead of directly implementing message queues in their applications.

Finta is an automated financial synchronization platform that integrates with data providers like Plaid and Stripe to sync data to destination integrations such as Notion, Airtable, Coda, and Google Sheets. The platform uses Inngest for orchestration and streamlining backend processes, ensuring accurate and efficient data synchronization. Key features of Inngest include concurrency with a key and invoke, which simplify function composability and orchestration. By using Inngest, Finta has improved its codebase maintainability and scalability while handling various rate limits and shared logic across different sync triggers.
