Cadence is a powerful, scalable, and fault-tolerant workflow orchestration framework that helps developers implement and manage complex workflow tasks. In most cases, developers contribute activities and workflows directly to their codebases, and they may not have a full understanding of the components behind a running Cadence application. We receive numerous inquiries about setting up Cadence in a local environment from scratch for testing. Therefore, in this article, we will explore the components that power a Cadence cluster.

There are three critical components that are essential for any Cadence application:

1. A running Cadence backend server.
2. A registered Cadence domain.
3. A running Cadence worker that registers all workflows and activities.

Let's go over these components in more details.

We've had a short break but now we are back. Welcome to the latest of our regular monthly Community Spotlight updates that gives you news from in and around the Cadence community!

Please see below for a roundup of the highlights:

Cadence Release 1.0​

Just in case you missed it - at the end of April Cadence v1.0 was officially released. This release is a significant milestone for the project and the community. It indicates that we are confident in the stability of the code that we can recommend it and promote it widely to more users. Kudos to everyone that worked together to make this release happen.

And the Uber team also gave Cadence a writeup on the Uber Engineering Blog so please take a look.

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.

The talk called Cadence: The New Open Source Project for Building Complex Distributed Applications will be given by Ender Demirkaya and Emrah Seker If you are planning to attend the Open Source Summit then please don't forget to attend the talk and take time catch up with Ender and Emrah!

Community Activity​

Our Slack #support channel has been very active over the last few months as we continue to get an continual stream of questions. Here are the stats:

• February 2023 : 16 questions asked
• March 2023 : 12 questions asked

All of these questions are being answered collaboratively by the community. Thanks everyone for sharing your knowledge and we are looking forward to receiving more of your questions!

Welcome back to the latest in our regular Cadence community spotlight updates where we aim to deliver you news from in and around the Cadence community! It’s been a few months since our last update, so I have a bunch of exciting updates to share.

Let’s get started!

Proposal for Cadence Plugin System​

Community member Mantas Sidlauskas drafted a thorough proposal around putting together a plugin system in Cadence. Aimed at enhancing the flexibility of integrating various components like storage, document search, and archival, this system encourages the use of external plugins, promoting innovation and reducing dependency complications. Your insights and feedback are crucial; learn more and contribute your thoughts at the link below:

A huge thank you to Mantas for initiating this work. This is an excellent example of how we can collaborate together to bring about new features that benefit us all.

Community Survey​

We've been talking about doing a community survey for a while and during February we sent it out. We are still collating the results so it's not too late to send in your response.

The survey takes 5 minutes and is your opportunity to provide feedback to the project and highlight areas you think we need to focus on.

Closing Down Cadence Office Hours​

We have been running Office Hours sessions every month since May last year. The aim was to give the community an opportunity to speak directly with some of the Cadence core developers and experts to answer questions on particular issues you may be having. We have found that the most preferred method for community questions has been the support Slack channel so have decided to stop this monthly call.

Thanks very much to Ender Demirkayaand the Uber team for making themselves available for these sessions.

Please remember that if you have question about Cadence or are facing a specific issue then you can post your question in our #support Slack channel. If you also post the details on StackOverflow with the cadence workflow tag then there will be a searchable history for others who encounter the same issue to find a solution.

I know we are a little early this month as many people will be taking some time out for holidays.

Happy Holidays​

We'd like to wish everyone happy holidays and to thank you for being part of the Cadence community. It's been a busy year for Cadence as we have continued to build a strong, active community that works together to solve issues and generally support each other.

Let's keep going!...This is a great way to build a sustainable community.

We are sure that 2023 will be even more exciting as we continue to develop Cadence.

Cadence @ Uber​

This month Uber Engineering published a really nice article on one of the ways they are using Cadence. The article is called How Uber Optimizes the Timing of Push Notifications using ML and Linear Programming.

The Uber team take you through the details of the problem that they are looking to solve, so you can understand the scope limitations and depedencies - so please take a look.

Cadence @ DeveloperWeek Enterprise​

DevNetwork run a series of conferences and during November Cadence was featured in at DeveloperWeek Enterprise. Ender Demirkaya and Ben Slater presented a talk called Espress Complex Business Logic as Code with Open Source Cadence!.

It is good to see that we are finding new channels for us to present the benefits of using Cadence. Huge hanks to Ben and Ender for the presentation and to everyone that attended.

Cadence Meetup Postponed​

It's always great to get the community together and we had planned to run another Cadence Meetup in early November. Unfortunately we didn't have enough time to get things organised so we've decided to postpone it. So please watch out for an announcement for the new Cadence meetup date.

Doordash Technnical Showcase Featuring Cadence​

We have had some great feedback from people who attended Technical Showcase that was run this month by Doordash. It featured their financial products but also highlighted some of the key technologies they use...and guess what Cadence is one of them!

If you missed the session then you will be happy to know that it was recorded and we've inlcuded a link to the the recording on Youtube.

Thanks to the Doordash team for running the session and helping support Cadence by sharing their knowledge.
