            Check your database username and password. If it's working before then it should work now and I don't think it's related to node of any of your dependancies.

            If it's never working, then try to change your password and try again. From your example the config is used by the mysql lib so there's no reason it picks your username and password but explicitly ignores your host.

            What are the limits on actorevents in service fabric?
            Asked 2021-May-31 at 12:22

            I am currently testing the scaling of my application and I ran into something I did not expect.

            The application is running on a 5 node cluster, it has multiple services/actortypes and is using a shared process model. For some component it uses actor events as a best effort pubsub system (There are fallbacks in place so if a notification is dropped there is no issue). The problem arises when the number of actors grows (aka subscription topics). The actorservice is partitioned to 100 partitions at the moment. The number of topics at that point is around 160.000 where each topic is subscribed 1-5 times (nodes where it is needed) with an average of 2.5 subscriptions (Roughly 400k subscriptions).

            At that point communications in the cluster start breaking down, new subscriptions are not created, unsubscribes are timing out. But it is also affecting other services, internal calls to a diagnostics service are timing out (asking each of the 5 replicas), this is probably due to the resolving of partitions/replica endpoints as the outside calls to the webpage are fine (these endpoints use the same technology/codestack).

            The eventviewer is full with warnings and errors like:

            After time spent with the support ticket we found some info. So I will post my findings here in case it helps someone.

            The actor events use a resubscription model to make sure they are still connected to the actor. Default this is done every 20 seconds. This meant a lot of resources were being used and eventually the whole system overloaded with loads of idle threads waiting to resubscribe. You can decrease the load by setting resubscriptionInterval to a higher value when subscribing. The drawback is that it will also mean the client will potentially miss events in the mean time (if a partition is moved).

            To counteract the delay in resubscribing it is possible to hook into the lower level service fabric events. The following psuedo code was offered to me in the support call.

            Run Spring Boot jar from standard Java application
            Asked 2021-Apr-05 at 17:08

            I have a large application with a database, Swing UI etc. Now I want to add a REST API for this application. Spring Boot allows easy generation of a REST API with useful features such as OpenApi documentation and authentication.

            However when I run the Spring Boot application from within the large non Spring Boot application the Spring Boot application gets confused by the dependencies of the parent application and fails to run.

            So my requirement is this: run a Spring Boot application from withing a non Spring Boot application without dependency interference from the parent application. I am currently running the Spring Boot application by adding the executable jar as a dependency and then calling org.springframework.boot.loader.JarLauncher.main(new String[0]); to run the Spring Boot application. I am not set on this way of doing it and any suggestions will be greatly appreciated.

            ANSWER

            Answered 2021-Apr-01 at 07:24

            Spring is a huge collection of highly configurable software libraries that can be used to setup (among other things) REST API endpoints and OpenAPI documentation and UI.

            Spring Boot is a project to simplify the process of using these libraries by applying an opinionated view of how to run them within a standalone process.

            By asking how to run a Spring Boot application within a larger application you are trying to get the benefit of the opinionated setup while violating the assumptions that the setup is based on. I guess in theory it might be possible using some sort of handrolled classloader isolation, but once you've solved the dependency problem you'll probably end up with class version conflicts, issues with configuration locations, etc. In short if it is possible at all the effort of doing so would negate the benefit.

            There are two ways of resolving the issue.

            1. Use Spring Boot to build your API as a standalone process. Configure the new process to talk to the same database as the existing application. If neccessary factor out any code common to both the existing application and the API (JPA entities, DAO classes etc) into a shared library. If you go with this option you will have the overhead of having to manage multiple kinds of process in your production environment, which is more complex - but has advantages in terms of decoupling scaling, release cycles, restart times. See the debate on microservices (https://martinfowler.com/articles/microservices.html).

            2. Use the Spring libraries that provide REST and OpenAPI features as part of your existing application, without using Spring Boot. You'll need to have SpringMVC set up in order to use @RestController annotated classes. If your existing application is a web application that's not too bad (https://docs.spring.io/spring-framework/docs/3.2.x/spring-framework-reference/html/mvc.html). If it's not run in a webserver already you'll have to launch the SpringMVC framework in an embedded webserver (https://devcenter.heroku.com/articles/create-a-java-web-application-using-embedded-tomcat). There's a good article on adding OpenAPI to an MVC application here: https://www.baeldung.com/spring-rest-openapi-documentation.

            I'm planning to develop a decentralized federated learning simulation environment using Tensorflow Federated API, so nodes are able to coordinate themselves to obtain data without the interference of the server.

            There are several ways to interpret this question I think, but in all of them the answer is no. All client-to-client communication in TFF must currently be intermediated by the server.

            A little more detail: TFF provides no intrinsics which model 'information exchange' between clients, though in principle such a thing can exist. That is, TFF is designed in such a way that this could be added. However, there are no plans to pursue this path in the immediate future.

            since a div is not a link, you can't use the selectors :link nor :visited. By simply removing them from your css, the result is way closer. Of course, you may have to implement a method to replace the use of :link and :visited
