We’re proud to announce that the Cadence project has joined the CNCF (Cloud Native Computing Foundation)®, the open-source foundation that hosts and maintains critical components of modern cloud-native infrastructure including Kubernetes®, Prometheus®, and Envoy® under the Linux Foundation®.

Are you struggling with uncontrolled concurrency when trying to process thousands of activities or child workflows? Do you find yourself hitting rate limits or overwhelming downstream services when running bulk operations? We've got great news for you!

Today, we're thrilled to announce Batch Future, a powerful new feature in the Cadence Go client that provides controlled concurrency for bulk operations. You can now process multiple activities in parallel while maintaining precise control over how many run simultaneously.

Cadence users, especially new users, often struggle with failed/stuck workflows and are unable to understand what is wrong with their workflow. This can now be addressed by a tool that runs on demand to check the workflow and provide diagnostics with actionable information via clear runbooks that users can follow. The overarching goal is to help cadence users understand what is wrong with their workflow

At Uber, we manage billions of workflows with lifetimes ranging from seconds to years. Over the course of their lifetime, workflow code logic often requires changes. To prevent non-deterministic errors that changes may cause, Cadence offers a Versioning feature. However, the feature's usage is limited because changes are only backward-compatible, but not forward-compatible. This makes potential rollbacks or workflow execution rescheduling unsafe.

To address these issues, we have made recent enhancements to the Versioning API, enabling the safe deployment of versioned workflows by separating code changes from the activation of new logic.

We are excited to announce the release of cadence-web v4.0.0—a complete rewrite of the Cadence web app. Cadence has always been about empowering developers to manage complex workflows, and with this release, we not only modernize the web interface by embracing today’s cutting-edge technologies but also strengthen the open source community by aligning our tools with the broader trends seen across the industry.

What's new in cadence-web v4.0.0​

• Revamped UI & Experience – A fresh, modern interface designed for better usability and efficiency.
• Multi-Cluster Support – The UI can now connect to multiple Cadence clusters.
• Performance Improvements – Faster load times, optimised API calls, and a smoother experience.

We’re excited to announce that all Cadence GitHub repositories have been consolidated under the cadence-workflow organization! 🎉

Previously, Cadence repositories were distributed across multiple organizations at Uber: uber, uber-go, uber-common. To improve developer cohesiveness and simplify access, the Cadence Core team has migrated all open-source repositories to the cadence-workflow organization.

For example, our main repository has moved from:

👉 uber/cadence

To its new home:

👉 cadence-workflow/cadence

You can find the full list of Cadence repositories here 👉 orgs/cadence-workflow/repositories

We’ve heard your feedback: deploying Cadence has been a challenge, especially with limited documentation on operational aspects. So far, we’ve only provided a few docker compose files to help you get started on a development machine. However, deploying and managing Cadence at scale requires a deep understanding of underlying services, configurations and their dependencies.

To address these challenges, we’re launching several initiatives to make it easier to deploy and operate Cadence clusters. These include deployment specs for common scenarios, monitoring dashboards, alerts, runbooks, and more comprehensive documentation.

Welcome to the latest of our regular monthly Community Spotlight updates that gives you news from in and around the Cadence community!

It's been a couple of months since our last update so we have a lot of updates to share with you.

Getting Started with Cadence​

Are you new to Cadence and want to understand the basic concepts and architecture? Well we have some great information for you!

Community member Chris Qin has written a short blog post that takes you through the three main components that make up a Cadence application. Please take a look and feel free to give us your comments and feedback.

Thanks Chris for sharing your knowledge and helping others to get started.

Cadence Go Client v1.0 Released​

This month saw the release of v1.0 of the Cadence Go Client. Note that the work done on this release was as a result of community feedback asking for it - so we are listening and responding to community needs.

Thanks very much to everyone who worked hard to get this release out!

We released a user survey earlier this year to learn about who our users are, how they use Cadence, and how we can help them. It was shared from our Slack workspace, cadenceworkflow.io Blog and LinkedIn. After collecting the feedback, we wanted to share the results with our community. Thank you everyone for filling it out! Your feedback is invaluable and it helps us shape our roadmap for the future.

Here are some highlights in text and you can check out the visuals to get more details:

Most of the people who replied to our survey were engineers who were already using Cadence, actively evaluating, or migrating from a similar technology. This was exciting to hear! Some of you have contacted us to learn more about benchmarks, scale, and ideal use cases. We will share more guidelines about this but until then, feel free to contact us over our Slack workspace for guidance.
