QUESTION
I have a Reactor Kafka application that consumes messages from a topic indefinitely. I need to expose a health check REST endpoint that can indicate the health of this process - Essentially interested in knowing if the Kafka receiver flux sequence has terminated so that some action can be taken to start it. Is there a way to know the current status of a flux (completed/terminated etc)? The application is Spring Webflux + Reactor Kafka.
Edit 1 - doOnTerminate/doFinally do not execute
...ANSWER
Answered 2021-Oct-12 at 07:57You can't query the flux itself, but you can tell it to do something if it ever stops.
In the service that contains your Kafka listener, I'd recommend adding a terminated (or similar) boolean flag that's false by default. You can then ensure that the last operator in your flux is:

How to pack the executable jar in zip using maven-assembly-plugin and not the Original file i.e. .jar.original
Currently, on providing maven-assembly-plugin as dependency, it packs the jar.original in the zip.
maven-assembly-plugin definition
...ANSWER
Answered 2021-Aug-20 at 09:11The spring-boot-maven-plugin is running after the maven-assembly-plugin. So at the time the assembly is created, there simply is no executable JAR file available yet. To fix the execution order just move the definition of the maven-assembly-plugin below the spring-boot-maven-plugin in your POM.

After installing anaconda on my windows 10 machine, and then I followed the following tutorial to set it up on my machine and run it with jupyter : https://changhsinlee.com/install-pyspark-windows-jupyter/

ANSWER
Answered 2021-Jun-23 at 19:42Similar error (and same answer) - Spark Kafka Data Consuming Package
Did you literally write ... after the --packages option?
The error is telling you to give a .py file or --class along with a JAR file containing your application code
And if you did give one, then it would seem the Spark user cannot access the D:\ drive path that you gave, and you likely need to use winutils chmod to modify that
If you want to run the code in Jupyter, you can add --packages there too

Answered 2021-Mar-27 at 09:20You are trying to compile LWJGL 2 code here. All the imports that it cannot find pertain to the verison 2 of LWJGL. The current version that you can get from the mentioned lwjgl site is 3 and version 3 is incompatible with version 2.
Either explicitly download LWJGL 2 from e.g. http://legacy.lwjgl.org/ or rewrite your code to work with LWJGL 3.
If you go the LWJGL 2 route, though, please note that it hasn't been actively maintained anymore for more than 6 years now.
