Thank you for both of your response. It is very helpful for me when I want to explore more on the concept of event streaming and able to use tools that I'm already familiar with like AMQ or RabbitMQ before jumping into Kafka. Just a quick browse on the resource, there are so much of Kafka to figure out.

When looking at Event Streaming, most are talking about Kafka. Is it possible to implement simple event streaming using traditional pub-sub capable messaging system like ActiveMQ, etc.? What are the tradeoffs?

According to Springboot 2 documentation we can use both Spring MVC and Spring WebFlux together. It says Spring WebFlux is either using Netty or Jetty; if we are using default server which is Tomcat, what is the implication of application size and memory footprint if it has both Tomcat and Netty/Jetty?

Similarly the documentation says we can just use WebClient, but the Springboot dependency only has a single WebFlux package. So it will pull in both server and client components of WebFlux, even though we might want to use WebClient only. Is there a way to just pull in the WebClient dependency?

I'm reading the Webflux guide & tutorial trying to understand the extend of asynchronisity of server side Webflux. If we have an async service, how does the client side receive the response when it is available? Aka how does client subscribe?

I don't see any example of it, unless the async is on the level how request call is handled but the overall service is still synchronous from client point of view.

Hi,

I'm curious on how to handle native npm packages when building Electron apps for multi platforms?

Thanks,

Almost all the examples and tutorials on Redux are implying a single store, but it seems it is possible to create multiple stores with Redux.

Is there a benefit for creating multiple stores? When should you use single or multiple stores?

Cheers,

Will CodeEnvy support non-rails ruby project? Such as plain Ruby or Sinatra?

Does CodeEnvy support custom keyboard binding like vi/emacs mode?

Well Kees,

It was the quoted answer that gave me the idea
So, from your follow up answer than it was case #2 of my understanding?

I never thought that looking at JavaRanch stat only. That was why case #1 cross my mind, maybe java-monitor is a product develop by JavaRanch as an SaaS service which allow us to download module to run on our server, but the data goes to JavaRanch cloud where we have to pay for the ability to view the data. Maybe another way for JavaRanch to earn some income to support this nice website

I'm sorry Kees from being slow. What should I look at to see JVM restart from that top-chart? Looking at sudden dip of Heap usage or dip in Max Heap?

Thanks for the chart Ulf. My follow up question was how java-monitor allows viewing of not-running JVM session? Does java-monitor has list of previous JVM sessions to view? Because those chart can be just showing current live session which has been alive for past 2-days or 1-week.

Whoa there Kees, your answer confused me a bit. You said

Java-monitor is a widget on JavaRanch that you can use to monitor your Java application servers.



Are you saying:
1. Java-monitor is monitoring our java application server, and the data is sent to JavaRanch which has web-based UI for us to view the data, so it is kind of SaaS offering from JavaRanch.
or
2. Java-monitor is a widget developed by JavaRanch and we can deploy on our server and monitor it on our local environment.

Ah, how does java-monitor allow viewing dead JVM session? How far in the JVM history does it keep? I assume this is also limited to the amount of storage space to keep the stats.

I'm looking at the website, it seems to imply live session monitoring only.
