Making HTTP content compression work in netty 4

jboss-netty-logo

Netty is really a great framework providing all the things needed to build a high performance HTTP server. The nice thing is, that nearly everything comes out of the box and has just to be put together in the right way. And content compression (gzip or deflate) is no exception.

The SQL Language’s Most Missing Feature

software-development-2-logo

SQL is also awesome in many ways. We can write out the most complex truths and facts and have the database tell us the answer in no time. But the SQL language is arguably the most beautiful programming language out there. It has so many caveats that people like me get ridiculously rich selling consulting services just to merely explain its semantics. One ...

Master/Slave Failover for Camel Routes

apache-camel-logo

One way to implement a master/slave failover pattern is to have a cluster of instances of an application where one instance (the master) is currently active and the other instances (the slaves) are on standby, ready to take over whenever the master fails. Some projects provide this kind of master/slave support out of the box: Creating a failover deployment for ...

Lesser-Known SQL Features: DEFAULT VALUES

software-development-2-logo

A lesser-known SQL feature is the DEFAULT keyword, which can be used in INSERT and UPDATE statements. Consider the following table, created using standard SQL syntax:                   CREATE TABLE timestamps ( id INTEGER GENERATED BY DEFAULT AS IDENTITY(START WITH 1), t TIMESTAMP DEFAULT CURRENT_TIMESTAMP, CONSTRAINT pk_values PRIMARY KEY (id) ) Now, in ...

On Java Collection Waste

java-logo

This article is about overhead posed by one of the most popular frameworks used – I bet there is close to no applications where the java.util.Collections is not used. The article is based on the fact that the framework provides default values for e.g. initial size of the collections. So we had a hypothesis that most people do not bother ...
