Asynchronous Logging in Mule 3.6


“Logs are like car insurance. Nobody wants to pay for it, but when something goes wrong everyone wants the best available” – Pablo Kraan

The phrase above fully explains why logs are important and why we need to be able to log as much information as possible without impacting performance. Because logging usually implies an I/O operation, it’s a naturally slow operation.

The Problem

Before Mule 3.6, logging operations were done using synchronous I/O. This means that the thread processing your message has to wait for the log message to be fully handled before it can continue.

Anypoint Studio January 2015 and Mule ESB 3.6 released


As part of our API-led Anypoint Platform January 2015 launch, I’m pleased to announce the next version of our runtime and tooling, Mule ESB 3.6 and Anypoint Studio January 2015. This release helps users more quickly connect to and design APIs based on a new HTTP connector that adopts a design-first and resource-based approach, all with higher performance. The new release of Anypoint Studio also improves the design experience, upgrades the base Eclipse runtime, and connects to Anypoint Exchange, our expansive library for connector and example information. Finally, major updates to AMQP and our SDLC tooling have been released.

A Road Trip

First off, let me apologize for the delay in this third part of the hypermedia sub-series. Christmas meant a warm trip back to Minnesota, a road trip through the Texas panhandle, and numerous snow storms in between — until finally I had the chance to cut through the mountainous desert of Southern California on my way back to beautiful San Francisco.


Now I understand some of you are probably wondering what any of that has to do with this post, other than it’s about 3 weeks after promised. One of the greatest challenges of the drive was battling my way through the snow and construction, and just hoping that the interstate would stay open (they literally close the interstates if it’s bad enough). But the one thing I could be sure of was that at every turn, between my steady GPS and road signs, I knew where I was going, and I knew when my path was being detoured or I couldn’t take a certain road… I knew this, because everything was nice and uniform.

Secure your APIs

Securing an API in Anypoint Platform is easy. In a previous post we showed how Anypoint Platform for APIs allows you to fully protect your API. We concluded then that the combination of HTTPS and OAuth 2.0 are a rule-of-thumb best practice for Web API security. In this post, we’ll take a deeper dive into the makeup of a security configuration in Anypoint Platform and explore in more detail the areas of Basic Authentication and OAuth2 Authorization in the context of Identity Management. We’ll also give you some pointers about when and how to use these two standards.

Security Manager

Central to authentication in Mule is the Security Manager. This is the bridge between standard mule configuration and Spring Security beans. In the example we build in this blog, we will use Spring Security to authenticate credentials against an LDAP server. We suggest you read the Spring Documentation on this topic if you want to delve further.

Let’s honor the future


This post is about fulfilling some expectations created by sci-fi movies, using Arduino and Nobel to expose RESTFul APIs for controlling physical devices.

The early-arriving future disappointment

This is the year that, according to some Hollywood prophets, cars will be finally flying, clothes will adjust their sizes to our bodies, trash will be combustible, and houses will be intelligent – though I never understood why they thought that an intelligent house would have a fax hanging on the wall. Come on? FAXES!

MuleSoft Performance and the Choke in the Wire


Hello from MuleSoft’s performance team!

This post describes a real-world tuning example in which we worked with a customer to optimize their Mule ESB application.

A customer presented us with an application that was to be a proxy to several endpoints. As such, it needed to be very lightweight since the endpoints introduced their own latency. We required the application to provide high throughput and minimal latency.

This real-world example shows how we helped the customer tune their application from a number of angles. We had quite an adventure: the performance metrics were a crime, the usual suspects were innocent, and there were some unexpected twists. But our story has a happy ending. What started at 125 tps and high latency ended at 7600 tps and low latency.

For more info on the tips and tricks we describe here, please see our Performance Tuning Guide.

Rise and Fall of the Black Box Developer


Let me start by stating that this is not a rant, it’s a look at my personal experience with interviewing candidates for technical Java positions. I guess that I first started to think about the following concepts when I read James Donelan’s post “Can Programmers Program?“. In that post he elaborates on some statistics from coding tests perform by developers applying for jobs. Those results indicated that many experienced developers were not able to solve simple problems. At first I thought that those statistics were blowing things way out of proportion, but then I started a retrospective down the memory lane and began to doubt.

The Harsh Reality of the State of Hypermedia Specs

Hypermedia sounds great in theory, but theory only goes so far. Where hypermedia really shines, or completely fails, is in implementation. Unfortunately, as hypermedia is still a relatively new aspect of web based APIs, there isn’t one specified way of doing things. In fact, you’ll find that even some of the most popular APIs operate completely differently from each other.

What is Hypermedia

One of the challenges to implementing and correctly using hypermedia in your REST API is first understanding what hypermedia is, and what it means to use hypermedia as the engine of application state (HATEOAS).

Unlocking Data to Transform Financial Services


Financial services information technology (IT) has transformed from order taker to strategic business partner. As part of this transformation, IT organizations are finding they must address key challenges with legacy modernization, data management and digital transformation.

MuleSoft has launched a three-part white paper series discussing these challenges and how financial institutions are overcoming them. In the first installment in our Connected Financial Institution whitepaper series, we discussed how aging back office systems, operational effectiveness and open source adoption are driving legacy modernization initiatives across the financial services industry. But the story doesn’t stop there. Modernizing legacy systems is only the first step in addressing the business imperatives faced by financial institutions.
