How we store and manage data has completely changed over the last decade. We moved from an ETL world to an ELT world, with companies like Fivetran pushing the trend. However, we don’t think it is going to stop there; ELT is a transition in our mind towards EL(T) (with EL decoupled from T). And to understand this, we need to discern the underlying reasons for this trend, as they might show what’s in store for the future. This is what we will be doing in this article. I’m the co-founder of Airbyte, the new upcoming open-source standard for data integrations. What Are the Problems With ETL? Historically, the data pipeline process consisted of extracting, transforming, and loading data into a warehouse or a data lake. There are serious disadvantages to this sequence. ETL is inherently rigid. It forces data analysts to know beforehand every way they are going to use the data, every report they are going to produce. Any change they make can be costly. It can potentially affect data consumers downstream of the initial extraction. Lack of Visibility Every transformation performed on the data obscures some of the underlying information. Analysts won’t see all the data in the warehouse, only the one that was kept during the transformation phase. This is risky, as conclusions might be drawn based on data that hasn’t been properly sliced. Lack of Autonomy for Analysts Last but not least, building an ETL-based data pipeline is often beyond the technical capabilities of analysts. It typically requires the close involvement of engineering talent, along with additional code to extract and transform each source...
September 08, 2020 / Paul Redmond Laravel 8 is now released and includes many new features including Laravel Jetstream, a models directory, model factory classes, migration squashing, rate-limiting improvements, time testing helpers, dynamic blade components, and many more features. Before we jump into the new features, we’d like to point out that starting with version 6, Laravel now follows semver and will release a new major version every six months. You can see how the release process works here. Laravel Jetstream Laravel Jetstream improves upon the existing Laravel UI scaffolding found in previous versions. It provides a starting point for new projects, including login, registration, email verification, two-factor authentication, session management, API support via Laravel, and team management. Models Directory Laravel 8’s application skeleton includes an app/Models directory. All generator commands assume models exist in app/Models; however if this directory doesn’t exist, the framework will assume the application keeps models within the app/ folder. Model Factory Classes Eloquent model factories are now class-based starting in Laravel 8, with improved support for relationships between factories (i.e., a user has many posts). I think you’ll agree how awesome the new syntax is for generating records via the new and improved model factories: Migration Squashing If your application contains many migration files, you can now squash them into a single SQL file. This file will be executed first when running migrations, followed by any remaining migration files that are not part of the squashed schema file. Squashing existing migrations can decrease migration file bloat and possibly improve performance while running tests. Improved Rate Limiting Laravel 8 brings improvements to existing rate limiting...
7+ Million HTTP requests per second from a single server It’s coming up to 2 years since I last posted about the performance of ASP.NET Core; during its preview, pre version 1.0. As preview 2 of has ASP.NET Core 3.0 has just been to released; it’s time to follow up, and find out how its evolved. ASP.NET Core 2.2 (Current) Looking at the latest run from the TechEmpower Benchmarks continuous results ASP.NET 2.2 is the 3rd fastest webserver (0.046% off the top spot); able to respond to 7 Million HTTP request per second: I recently saw another post; about a different product, where throughput that was measured monthly; so if we use that time period, that’s 18.1 trillion HTTP requests per month. It’s also an extraordinary amount of bandwidth; enough to continuously saturate a 10GBps link. These results are with the webserver and load tester running inside Docker containers, on two different physical Linux machines *; connected with a 10GbE network. All this throughput from a single server! ASP.NET Core is fast on Linux (and on Windows). How does it compare to other well known servers? In these “platform” comparisons that’s: Internet Facing Server ASP.NET Core’s Kestrel Webserver; which is used in these benchmarks, is an edge server so can be used as an internet facing webserver, as explained in the documentation: It doesn’t need a second webserver acting as a reverse-proxy server in front and can go full speed. It also works with reverse-proxies if that fits more with your infrastructure. Data Access Performance I often hear the defeatist argument that performance like this doesn’t matter because “my...
April 06, 2020 A few years back, creating mobile applications using Python was almost a pipedream. But today, even Python has entered into the race that follows the phrase, “Write once, deploy everywhere”. Surprised right? Well, yes, using a few suites of tools it is possible to build mobile applications using Python. Things have shuffled and Python is now capable of delivering Android and iOS platforms. Thanks to the two major python app development frameworks, Kivy, and BeeWare. In this article, we have run a small comparison between Kivy Vs BeeWare that will help you in having a better understanding of both. We can say it was the need of the hour for the Python community to come up with the solution that allows direct deployment of apps on iOS and Android. Millions of Python lovers awaited the release of the frameworks that would allow them to write mobile applications using Python. The two frameworks, Kivy and BeeWare added on to the Python’s strength of This allowed developers to take advantage of Python for mobile applications. These framework libraries play a major role and you can easily build applications using Python’s clear syntax. Let’s have a look at them. Let’s understand the Kivy framework: Kivy is an open-source Python library that can be used to deploy mobile applications across multiple platforms. The framework was released in the year 2011 and extends its support to multitouch events, regular keyboard inputs as well as mouse inputs. Kivy has the potential to act and strengthen with the platform they are deployed on. It is used to create graphical user interfaces that can...
Just when you thought things couldn’t get any stranger… Donald Trump has fired his cybersecurity chief, Christopher Krebs, after he debunked Trump’s election fraud claims. Trump has been tweeting for angrily for a couple of weeks, about what he perceives to be voter fraud and even claiming he won. He’s also sharing tweets with the information he hopes will reverse the calls for Biden. The Radical Left Democrats, working with their partner, the Fake News Media, are trying to STEAL this Election. We won’t let them! — Donald J. Trump (@realDonaldTrump) November 16, 2020 I won the Election! — Donald J. Trump (@realDonaldTrump) November 16, 2020 Wow! Michigan just refused to certify the election results! Having courage is a beautiful thing. The USA stands proud! — Donald J. Trump (@realDonaldTrump) November 18, 2020 Trump then tweeted that he had fired his chief of cybersecurity. In it, he claims that Krebs made a “highly inaccurate” statement, insisting again that there were instances of fraud and improprieties. …votes from Trump to Biden, late voting, and many more. Therefore, effective immediately, Chris Krebs has been terminated as Director of the Cybersecurity and Infrastructure Security Agency. — Donald J. Trump (@realDonaldTrump) November 18, 2020 Like many of Trump’s tweets of late, Twitter has added a notification stating that his claims are disputed. The tag has turned into a meme over the last few days, of people posting to make their own tweets look disputed. Krebs spoke to NBC News on Tuesday night after the firing: “I’m proud of the work we did at CISA… I’m proud of the teammates I had at CISA. We...
