  • Job APIs and scheduling services (preview): The Job API is a scheduler for scheduling future tasks that can be executed at specific times or at specific intervals. This applies to a variety of scenarios such as automated database backups, periodic data processing and ETL, email notifications, maintenance tasks and system updates, and batch processing.Dapr's Work API ensures that tasks in these scenarios are executed consistently and reliably, increasing efficiency and reducing the risk of errors. In addition, Dapr introduces a new scheduling service, a control plane service for scheduling actor alerts.

  • API Updates: Dapr v1.14 has updates to the API to support new features and components. These updates include the introduction of the Job API, which is used to schedule future tasks, either at a specific time or at a specific interval.Performance improvements to increase throughput and reduce latency when using Actor and Workflow.Actor multi-tenancy uses namespaces to isolate identical Actor types and prevent name conflicts.

Deployment for per-node deployment using Kubernetes Daemonset or per-cluster deployment using Deployment.
  • Building Blocks for Dapr: Dapr provides a set of building blocks for distributed systems to build microservice applications in a standard way and deploy them to any environment. These building block APIs are independent, meaning that any number of them can be used in an application.

  • platform independence: Dapr is platform-agnostic and can run applications locally, in any Kubernetes cluster, on virtual or physical machines, and in other Dapr-integrated hosting environments. This makes it possible to run microservice applications in the cloud and at the edge.
