azure-event-hubs-java is a Java library typically used in Cloud, Azure applications. azure-event-hubs-java has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has low support. You can download it from GitHub.

Azure Event Hubs is a highly scalable publish-subscribe service that can ingest millions of events per second and stream them into multiple applications. This lets you process and analyze the massive amounts of data produced by your connected devices and applications. Once Event Hubs has collected the data, you can retrieve, transform and store it by using any real-time analytics provider or with batching/storage adapters. The Azure Events Hubs client library for .NET allows for both sending and receiving of events. Most common scenarios call for an application to act as either an event publisher or an event consumer, but rarely both. An event publisher is a source of telemetry data, diagnostics information, usage logs, or other log data, as part of an embedded device solution, a mobile device application, a game title running on a console or other device, some client or server based business solution, or a web site. An event consumer picks up such information from the Event Hub and processes it. Processing may involve aggregation, complex computation and filtering. Processing may also involve distribution or storage of the information in a raw or transformed fashion. Event Hub consumers are often robust and high-scale platform infrastructure parts with built-in analytics capabilities, like Azure Stream Analytics, Apache Spark, or Apache Storm.

            Azure Event Hub ServiceBusException causing skipped messages
            Asked 2017-Apr-06 at 20:33

            We are using the Azure Java event hub library to read messages out of an event hub. Most of the time it works perfectly, but periodically we see exceptions of type "com.microsoft.azure.servicebus.ServiceBusException" occur that correspond to times when messages seem to be skipped that are in the event hub.

            Here are some examples of exception details:

            • "The message container is being closed (some number here)."
              • This generally hits multiple partitions at the same time, but not all.
              • The callstack only includes com.microsoft.azure.servicebus and org.apache.qpid.proton.
            • "The link 'xxx' is force detached by the broker due to errors occurred in consumer(link#). Detach origin: InnerMessageReceiver was closed."
              • This is generally tied to com.microsoft.azure.servicebus.amqp.AmqpException exceptions.
              • The callstack only includes com.microsoft.azure.servicebus and org.apache.qpid.proton.

            Example callstack:

            This error DOESN'T SKIP any messages - it will throw an Exception, when it shouldn't have. This will result in EPH to RESTART the affected Partitions' Receiver. If the application using EventHubs javaclient doesn't handle the errors - they may experience loss of messages.

            This is a bug in our retry logic - in the current version of EventHubs JavaClient - until 0.11.0.

            Here's the corresponding issue to track progress.

            In EventHubs service - these errors happen if - for any reason - the Container hosting your EventHubs' code has to close (for the sake of the explanation, imagine we run a set of Container's - like DockerContainers for every EventHub namespace) - this is a transient error - this Container will eventually be opened in another Node.

            Our javaclient-retry logic should have handled this error and should have retried - Will keep this thread posted with the fix.

            EDIT

            We just released 0.12.0 - which fixes this issue.

            Thanks! Sreeram
