January 2024 Summaries

The blog post, a public copy of a newsletter from January 26th, 2023, highlights the growth of the developer community and previews an exciting 2024 with more meetups, conferences, and technical updates. It announces the Public Preview of the Temporal Cloud Operations API and API Keys, allowing for the automation of various management activities. SDK updates include PHP 2.7's new features and optimizations and TypeScript 1.9's experimental Workflow Update feature with improved resource efficiency. A series of webinars will explore the architecture of Temporal Cloud, and several upcoming meetups and events are planned, including collaborations with Bitovi and Airwallex, and participation in the DevWorld Conference. The post also mentions the Replay 2024 conference and offers guides on application reliability, converting Cron jobs to Temporal Schedules, and managing long-running workflows.

Long-running workflows are processes that do not have a definite end, which can last from less than a second to many years depending on the application. These workflows are also known as Entity Workflows and are similar to an Actor Model where a Workflow Execution represents one occurrence of some kind of entity like a customer's lifecycle through their purchasing journey or a product inventory. Temporal ensures the durability of these long-running workflows by recording state changes, known as Events, in its Event History. When the Event History limit is reached, Continue-As-New can be used to clear the history and start a new instance with the same Workflow ID. Signals are used to send data into a Workflow while Queries allow retrieval of application-specific data from a Workflow. Updates combine both operations in one.

Infrastructure reliability is crucial for applications that depend on multiple microservices and external dependencies. However, even with effective tools like Kubernetes and Istio, infrastructure failures can occur. To ensure application reliability, it's essential to focus on the overall workflow rather than individual services. Temporal Workflows enable automatic resumption of user requests when a process is interrupted due to infrastructure problems, leading to better overall application reliability even with unreliable infrastructure components.

In 2023, Temporal made significant progress in improving the developer experience with Durable Execution. The company's open-source community grew steadily, with over 8.8k stars on GitHub and a Slack workspace of more than 10,000 members. Temporal held meetups around the world, reaching thousands of developers. In addition to commercial success, the company launched a Startups program and a Partner Ecosystem. Temporal added new features such as Workflow Update, Temporal Schedules, and Timeline View, while also expanding its SDKs to six fully supported options. The company's managed service matured with the addition of three new regions and enhanced automation capabilities. The Replay Conference saw a significant increase in talks and attendees, featuring speakers from various companies discussing their experiences using Temporal. Training, support, and content were also improved to help developers learn Temporal more easily. Looking ahead to 2024, Temporal plans to launch new capabilities such as multi-region availability, self-serve signup, and Google Cloud Platform options for Temporal Cloud.
