vertx

In Vert.x, Vertx interfaces are the most important interface, and the underlying functionality of Vertx-core is provided in this interface. In this article we will analyze Vertx the internal implementation of the interface system and the creation process. This article corresponds to the vert.x version of 3.2.1.Vertx In

Cloudopt Next is a Kotlin, vertx-oriented, next-generation, ultra-lightweight microservices framework that allows you to handle URL parsing, data encapsulation, JSON output, and more, radically reducing development time and improving the development experience. Cloudopt next absorbs the ideas of spring Boot, jfinal, Resty, VERTX and other outstanding projects, with a very good development experience and a v

programming language, but a bit cooler is that we don't force you to use Java Api,javascript or Ruby directly, after all, different languages have different ways and syntax, And it's strange to force Java syntax to be used in Ruby. In return, we automatically have the same language habits for each language generator and Java API. From now on, we use the kernel instead of the Vert.x core module If you are using Maven or Gradle, add the following dependencies to your app's dependencies (dependenc

In this article, we'll see how to use Hsql in vert.x applications, as well as using arbitrary JDBC, and the asynchronous API provided by Vertx-jdbc-client, the code for this article is GitHub. Asynchronous? A very important feature of Vert.x is its asynchronous nature. Using an asynchronous API, you do not need to wait for results to return, and Vert.x will actively notify you when a result returns. To illustrate this, let's look at a simple example

Write a C language experiment to use an algorithm to determine whether a point is within the polygon. The code for C is as follows: int pnpoly (int nvert, float *vertx, float *verty, float testx, float testy) { int I, j, C = 0; for (i = 0, j = nvert-1; i if ((verty[i]>testy)! = (verty[j]>testy)) (Testx (ver TY[J] -verty[i]) + vertx[i])) c =!

must know the consumer, otherwise there is no way to send the message. The CSP model is similar to the producer-consumer model we mentioned in multithreading, and the core difference I feel is that there is something like green thread in the CSP model. The green thread in Golang is called the co-process, and the co-process is also a very lightweight scheduling unit that can be created quickly and with very low resource usage. Actor to some extent need to change our way of thinking, and the CSP

requests per day. However, for most applications, the performance and scalability of the API gateway is also important. Therefore, it makes sense to create an API gateway that supports synchronous, non-blocking I/O. There are already different technologies that can be used to implement an extensible API Gateway. On the JVM, a framework based on NIO technology, such as Netty,vertx,spring reactor or JBoss Undertow, is used. node. JS is a non-JVM popula
