![]() ![]() ![]() A new command built into the Airflow CLI that you can invoke to reserialize DAGsĪirflow 2.3 implements the dynamic task mapping API first described in AIP-42 - a genuine game changer for the hundreds of thousands of teams that depend on Airflow today.New ability to store Airflow connections in JSON instead of URI format.A new listener plugin API that tracks TaskInstance state changes.A new REST API endpoint that lets you bulk-pause/resume DAGs.A new LocalKubenetesExecutor you can use to balance tradeoffs between the LocalExecutor and KubernetesExecutor.A new, improved grid view that replaces the tree view.Dynamic task mapping lets Airflow trigger tasks based on unpredictable input conditions.So Airflow 2.0 and 2.2 were big releases - but 2.3 is arguably even bigger. This gives you new options for accommodating long-running tasks, as well as for scaling their Airflow environments. And then there’s Airflow 2.2, which introduced support for deferrable operators, allowing you to schedule and manage tasks to run asynchronously. After all, Airflow 2.0 debuted with a refactored scheduler that eliminated a prior single point of failure and vastly improved performance. Our team of Developers, Application Specialists, Trainers and Testers are located globally in far-east Asia, India, Europe and North America.Believe it or not, Airflow 2.3 might be the most important release of Airflow to date. Our mission is to sustain the future of OpenFOAM as the highly functional, freely available and open source CFD software, offering a long-term and viable complement to CFD codes which are constrained by licence costs and multi-user, multi-processor cost inflation. OpenCFD Ltd is a wholly owned subsidiary of the ESI Group. the owner of the OpenFOAM Trademark directly released its version of OpenFOAM from January 2016 to the present day. continued to manage and develop OpenFOAM, preparing all releases whose IP was later transferred to and released by OpenFOAM Foundation Inc. OpenCFD Ltd has been managing and developing OpenFOAM since its debut in 2004, releasing all versions prior to 8th August 2011, when OpenCFD transferred the IP rights to the US foundation "OpenFOAM Foundation, inc.". OpenFOAM releases are scheduled every six months in June and December. Tests are designed to assess regression behaviour, memory usage, code performance and scalability. The process of code evaluation, verification and validation includes several hundred daily unit tests, a medium-sized test battery run on a weekly basis, and large industry-based test battery run prior to new version releases. Quality assurance is based on rigorous testing. It is independently tested by ESI-OpenCFD's Application Specialists, Development Partners and selected customers, and supported by ESI's worldwide infrastructure, values and commitment. OpenFOAM is professionally released every six months to include customer sponsored developments and contributions from the community. ![]() OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to acoustics, solid mechanics and electromagnetics. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. ![]() OpenFOAM is the free, open source CFD software developed primarily by OpenCFD Ltd since 2004. ![]()
