Announcing QStash v2
Blog post from Upstash
QStash 2.0 is a significant update to the message queuing system, featuring a complete rewrite focused on enhanced reliability and scalability. Key features include Dead Letter Queues (DLQs) for handling failed messages, ensuring they can be investigated, resolved, and republished, thus improving application reliability. The new architecture supports horizontal scalability to accommodate increased workloads, and developers now have the flexibility to use custom methods beyond POST by specifying headers. Users are encouraged to migrate from QStash v1, which will be deprecated on December 1, 2023, to take advantage of the new /v2/... API endpoints, with guidance provided through a migration guide. The update aims to cater to both small projects and large enterprise systems, inviting feedback through social media platforms.
