Distributed Systems Diagnostics and Instrumentation Packages Targeting Open Telemetry Beta for MongoDB and NServiceBus Published That's...a long title. I've published release packages for System.Diagnostics support for NServiceBus and MongoDB: NServiceBus.Extensions.DiagnosticsMongoDB.Driver.Core.Extensions.DiagnosticSourcesAnd published new beta packages targeting the beta release of OpenTelemetry: NServiceBus.Extensions.Diagnostics.OpenTelemetryMongoDB.Driver.Core.Extensions.OpenTelemetryThe Diagnostics packages are
Distributed Systems Diagnostics and Instrumentation Packages for MongoDB and NServiceBus Published As part of the end-to-end diagnostics and tracing blog series, I had an end goal of eventually publishing out NuGet packages for diagnostics (Activity and DiagnosticSource). I'm happy to announce that I've released 4 packages to NuGet: NServiceBus.Extensions.DiagnosticsNServiceBus.Extensions.Diagnostics.OpenTelemetryMongoDB.Driver.

Microservices Life Beyond Distributed Transactions: An Apostate's Implementation - Conclusion Posts in this series: A Primer Document Coordination Document Example Dispatching Example Failures and Retries Failure Recovery Sagas Relational Resources Conclusion We started out with a common, but nearly always overlooked problem: how do we reliably coordinate activities between different transactional resources? The question

Distributed Systems Dealing With Optimistic Concurrency Control Collisions Optimistic Concurrency Control (OCC) is a well-established solution for a rather old problem - handling two (or more) concurrent writes to a single object/resource/entity without losing writes. OCC works (typically) by including a timestamp as part of the record, and during a
REST Swagger, the REST Kryptonite Swagger, a tool to help design, build, document, and consume RESTful APIs is ironically kryptonite for building actual RESTful APIs. The battle over the term "REST" is lost, where "RESTful" simply means "an API over HTTP" but these
