Orleans v3.3.0 Release Notes

Release Date: 2020-09-09 // over 3 years ago

  • 👌 Improved diagnostics for long running, delayed, and blocked request:

    🚀 This release includes improvements to give developers additional context when a request does not return promptly. PR #6672 added these improvements. Orleans will periodically probe active grains to inspect their message queues and send status updates for certain requests which have been enqueued or executing for too long. These status messages will appear as warnings in the logs and will also be included in exceptions when a request timeout occurs. The information included can help a developer to identify what the grain is doing at the time of the request. For example, which messages are enqueued ahead of this message, and which messages are executing, how long they have been executing, how long this message has been enqueued, and the status of the grain's TaskScheduler.

    📦 Microsoft.Orleans.Hosting.Kubernetes NuGet package (3.3.0-beta1) for tighter integration with Kubernetes

    📚 This release adds a new pre-release package, Microsoft.Orleans.Hosting.Kubernetes, which adds richer integration for users hosting on Kubernetes. The package assists users by monitoring Kubernetes for silo pods and reflecting changes in cluster membership. For example, when a Pod is deleted, it is immediately removed from Orleans' membership. In addition, the package configures EndpointOptions and `ClusterOptions' to match the Pod's environments. Documentation and a sample project are expected in the coming weeks, and in the meantime, please see the original PR for more information: #6707.
