Understanding Reactor Pattern with Java NIO

Why non-blocking IO A typical server application, such as a web server, needs to process thousands of request concurrently. Therefore, the modern web server needs to meet the following requirements. Handling of thousands of connections simultaneously (significant number of connections may be in idle state as well) Handling high latency connections Request/response handling needs to be decoupled Minimize latency, maximize throughput and avoiding unnecessary CPU cycles Hence, to cater to such requirements, there can be several possibilities in the server application architecture. Having a pool of sockets for each client, and periodically polling them: This is the most straightforward approach; however, it is more or less impractical without non-blocking sockets. This is extremely inefficient and never scales with the increasing number of connections. Thread per socket: This is the conventional approach and was initially used in some applications and this is the only practical solution wi...

We have just released WSO2 ESB 4.5.0, the High Performance Open Source ESB,which is the first ESB version based on enhanced WSO2 Carbon 4 platform.  I would like to give an high level overview of WSO2 ESB 4.5.0's new features and improvements.  XPath 2.0 and XSLT 2.0 support In most of the integration scenarios, we need to leverage the new features of XPath 2.0 and XSLT 2.0. WSO2 ESB 4.5.0,  comes with XPath 2.0 and XSLT 2.0 support. Also, we did a major performance enhancement with the introduction of Saxon as the deafult XSLT/XPath engine.   JSON  Integration is all about handling diverse message types. In that context, JSON plays a major role as numerous APIs are exposed via JSON.  In ESB 4.5.0, we introduce a brand new JSON implementation, which can be used to Streaming JSON (JSONStreamFormatter and JSONStreamBuilder) messages through ESB. In case, if we need to mediate message based on the message content (rather than streaming), th...

Nowadays Sri Lankan music stream is flooded with a lot RnB and Hiphop music and many people merely want to listen to such styles of music. And all the radio stations are backing such music and ruining the natural music taste of Sri Lankans. All those commercial oriented artists tend to release their 5-6 tracks per a month. This is something simply related to the quantity and they simply want to create a music track using computers and other equipments. Once they create the track there are people who can write some strange words to tally with the track and the beat. Finally they’ll come up with a music video and all the TV stations eagerly waiting to play their music video.This is the story of Iraj, BnS, .. (you name it) But .. They have forgotten the fact that there are some (I think its few ) people in Sri Lanka who still loves the instinctive slow music (mood songs) which is a blend of soothing voices and acoustic music. Kasun Kalhara is one of the exceptions thrown from the Sri Lan...
