Setting up a data warehouse is the first step towards fully utilizing big data analysis. Still, it is one of many that need to be taken before you can generate value from the data you gather. An important step in that chain of the process is data modeling and transformation. This is where data is extracted, transformed, and loaded (ETL) or extracted, loaded, and transformed (ELT).

By Anupom Syam Background At Netflix, our current data warehouse contains hundreds of Petabytes of data stored in AWS S3 , and each day we ingest and create additional Petabytes. At this scale, we can gain a significant amount of performance and cost benefits by optimizing the storage layout (records, objects, partitions) as the data lands into our warehouse.

Dynatrace news. Distributed tracing is a method of observing requests as they propagate through distributed cloud environments. Distributed tracing follows an interaction by tagging it with a unique identifier, which stays with it as it interacts with microservices, containers, and infrastructure. It can also offer real-time visibility into user experience, from the top of the stack right down to the application layer and the large-scale infrastructure beneath.

Distributed clusters might encounter performance problems or unpredictable failures, especially when they are running in the cloud. Of all the kinds of failures, kernel failures may be the most difficult to analyze and simulate. A practical solution is Berkeley Packet Filter (BPF), a highly flexible, efficient virtual machine that runs in the Linux kernel.

Applications used in the field of Big Data process huge amounts of information, and this often happens in real time. Naturally, such applications must be highly reliable so that no error in the code can interfere with data processing. To achieve high reliability, one needs to keep a wary eye on the code quality of projects developed for this area. The PVS-Studio static analyzer is one of the solutions to this problem.

Team Topologies has significantly advanced the discussion on organisation design for technology companies. The next step is to determine what Team Topology boundaries align to…what should Stream-aligned (and other) teams own? When organising technology teams to build digital products and services, it is necessary to determine which parts of the product, user experience, and technology each team owns.

Regression testing is one of the most critical aspects of quality assurance. It helps developers to check for issues that are introduced by new additions to their codebase or due to a bug fix. The aim is to check all those pieces of code that could be impacted due to these changes. It goes without saying that adopting effective regression testing strategies can save development teams hundreds of hours of debugging.

Whenever a new methodology or a new system is introduced, with it – certain terms and guidelines are introduced too. These terms and guidelines are meant to be followed to ensure maximum output. But during implementation, some of these guidelines might be deemed not-so-important and might not be followed. Similar has been the case with Scrum Agile Methodology.

The easiest way to use it is through the Chrome DevTools panel. Once you open the DevTools, you will see a “Lighthouse” tab. Clicking the “Generate report” button will run a series of tests on the web page and display the results right there in the Lighthouse tab.

Swift for iOS with Xcode or Java, Kotlin with Android Studio is some of the notable examples. However, in recent times, it is abundantly clear that a cross-platform framework like Flutter has been on the rise, and it provides native performance for iOS and Android with a single-code line.

The installation steps from HammerDB-4.0-Win-x64-Signed-Setup.exe is identical to HammerDB-4.0-Win-x64-Setup.exe and the contents in the installed directory are the same. The key difference between the 2 installers is that the Signed Setup has been signed with a code signing certificate, whereas for the unsigned installer you can verify the installer itself manually with the provided checksums.

Responsive Web Design (RWD) is a term that was defined by Ethan Marcotte in 2010 according to which, design and development of web pages should be responsive to different screen size, platform, and orientation. Basically, the idea was to create web pages that look good on all devices and size screens. Earlier, people only had a desktop and a limited number of browsers to surf the internet.
