Function Metrics is a new beta feature announced by Inngest that provides observability into how background jobs and workflows are operating. This feature allows users to view function throughput and SDK request throughput charts on each function dashboard, with the option to show concurrency settings limits being hit. The goal of Function Metrics is to simplify operations for users by providing useful information out-of-the-box, unlike existing tools such as BullMQ, Sidekiq, Celery, Oban, and Kafka. Future improvements include alerting features and enhanced metrics capabilities, with user feedback being crucial in shaping the future of Inngest.

The article discusses how to create user-defined workflows in Next.js applications using Sanity and Inngest. It highlights the challenges of hardcoded workflows and the need for external tools like Zapier and Make, which can be difficult to integrate into a development environment. The author suggests using Sanity for the database and end-user UI, Inngest for handling queuing and durability issues with execution, and Next.js for serving serverless functions. The article provides a step-by-step guide on how to set up these tools and implement a simple data model workflow. It also demonstrates how to execute the workflow in serverless functions using Next.js.

Inngest has released TypeScript SDK v3.0, which includes a refactored core loop, improved function versioning, enhanced parallelism, support for top-level await, and paves the way for multi-language support. The new SDK introduces a shared hashing scheme across all language SDKs, allowing live-migrating functions across languages and clouds. Additionally, it improves function versioning, enabling hotfixes and logic changes without errors or failures. Future plans for v3 include invoke, debouncing, strict mode, and version switching features.
