NFD consists of the following software components: The NFD Operator is based on the Operator Framework an open source toolkit to manage Kubernetes native applications, called Operators, in an effective, automated, and scalable way. The processing-time mode can be suitable for certain applications with strict low-latency requirements that can tolerate approximate results.

Provided APIs # To show the provided APIs, we will start with an example before presenting their full functionality. Scala API Extensions # In order to keep a fair amount of consistency between the Scala and Java APIs, some of the features that allow a high-level of expressiveness in Scala have been left out from the standard APIs for both batch and streaming. This document describes how you can create and manage custom dashboards and the widgets on those dashboards by using the Dashboard resource in the Cloud Monitoring API. Failover strategies decide which tasks should be restarted While you can also manage your custom How to use logging # All Flink processes create a log text file that contains messages for various events happening in that process. Task Failure Recovery # When a task failure happens, Flink needs to restart the failed task and other affected tasks to recover the job to a normal state. These logs provide deep insights into the inner workings of Flink, and can be used to detect problems (in the form of WARN/ERROR messages) and can help in debugging them. Processing-time Mode: In addition to its event-time mode, Flink also supports processing-time semantics which performs computations as triggered by the wall-clock time of the processing machine.
