One embedded mongo to rule them all

Have you ever wondered what’s happening behind the scenes when you run tests using spring boot? Usually, you don’t care until it’s working in a predictable way. Once you encounter performance issues, your PC starts to lag, a single test executes in a couple of seconds instead of milliseconds, then you start digging. Most of the time, you end up with a single culprit — the spring context caching mechanism. It’s a great “tool” to speed up your tests, but you must be aware of all the consequences it entails.

Investigation

Let’s take a step back and start with a problem we had in the project. We have a spring boot application with mongo as storage. We have more than five hundred tests which start up a spring context and use embedded mongo beneath. A couple of weeks ago, we decided to bump up the version of embedded mongo to have it aligned with the one we have in real. A small change in gradle.properties and application.properties, rerun all test suites and … my computer stopped responding. Upsss… I needed a hard reset to bring it back to life ;-)

We reverted the change but a few days later, we decided to investigate the problem.

Big Data Follows One Farm, One Data Set Rule Overwhelming To Farmers

The digital world has transformed several businesses with significant impacts on data analytics. The vast type of knowledge available to view is expected to exceed 44 zettabytes by 2022 and has proved to have been of tremendous benefit to several sectors and big companies.

A few companies that get an advantage from big data consulting services are banking, airline, tourism, hospitality, automotive, athletic, entertainment industries, and even the farming sector. The collection could go on and on through big data could be a tremendous possession of an industry expert. By the end of 2021, the company’s acceptance of big data will go to 53 percent. Agriculture struggles to be symbiotic towards the business in the clarification of the information produced.

One industry that can enormously get profit from big data is the rural area. Indeed, the horticultural business likewise can utilize information from numerous points of view and advantage from it extraordinarily. Big data gets an inventive methodology in pretty much every area of the world, so for what reason would horticulture be given up.

Big data is quite an incredible power that it unquestionably can change the agricultural space. Today ranchers must comprehend and esteem innovation to settle on choices all the more rapidly and not linger behind the imaginative methodologies. As smart types of machinery and instruments yield up on farm statistics produce in huge amounts. Possibility, farming developments would develop to be progressively data-enabled as well as data-driven.

How to Install Red Hat Decision Manager 7.7

There are many ways to introduce business logic into your development projects, but there is only one way to ensure that it scales.

When you start out as a developer you don’t even realize that those if-then-else statements are business logic. You don’t recognize case statements as logical choice moments in the flow of your application. It’s ok, that’s where it all starts for everyone.

Over time you start to see these logical constructs growing and becoming more less manageable. Who wants to continue to add another else if statement to the growing chain of logic in their program?

Enter rule engines and the ability to externalize all of your development projects business logic. Not only that, it can become a repository of reusable logic for your entire application landscape and give your business users insights into how their applications can be changed without new releases.

All this and more is possible when you learn to use and add rule engines to your developer toolbox.

Open source rule engine

One of the well known open source rule engines is the Red Hat Decision Manager, a product that flows from the upstream Drools projects. In the past I’ve kept you up to date on installing Red Hat Decision Manager with my easy install project.

Well here’s an update that installs the latest business logic tooling for your development projects in just minutes on your very own machine.

Not only that, it’s done in just three easy steps, so let’s take a closer look and see if I’m pulling your leg or telling the truth about how easy this installation can be.

Just three easy steps to a fully installed and configured Red Hat Decision Manager.
