Incremental Jobs and Data Quality Are On a Collision Course

Aggregated on: 2025-01-01 18:10:41

If you keep an eye on the data space ecosystem like I do, then you’ll be aware of the rise of DuckDB and its message that big data is dead. The idea comes from two industry papers (and associated data sets), one from the Redshift team (paper and dataset) and one from Snowflake (paper and dataset). Each paper analyzed the queries run on their platforms, and some surprising conclusions were drawn — one being that most queries were run over quite small data. The conclusion (of DuckDB) was that big data was dead, and you could use simpler query engines rather than a data warehouse. It’s far more nuanced than that, but data shows that most queries are run over smaller datasets. Why?

Understanding JavaScript Promises: A Comprehensive Guide to Create Your Own from Scratch

Aggregated on: 2025-01-01 13:10:41

Asynchronous programming is an essential pillar of modern web development. Since the earliest days of Ajax, developers have grappled with different techniques for handling asynchronous tasks. JavaScript’s single-threaded nature means that long-running operations — like network requests, reading files, or performing complex calculations — must be done in a manner that does not block the main thread. Early solutions relied heavily on callbacks, leading to issues like “callback hell,” poor error handling, and tangled code logic. Promises offer a cleaner, more structured approach to managing async operations. They address the shortcomings of raw callbacks by providing a uniform interface for asynchronous work, enabling easier composition, more readable code, and more reliable error handling. For intermediate web engineers who already know the basics of JavaScript, understanding promises in depth is critical to building robust, efficient, and maintainable applications.

The Power of Docker and Cucumber in Automation Testing

Aggregated on: 2024-12-31 18:10:41

Automation testing is a must for almost every software development team. But when the automation suite consists of many scenarios, the running time of automation suites tends to increase a lot, and sometimes, rather than helping a team to reduce the turnaround time of testing, it doesn’t help in a much-expected way. Thus, there is a need for parallelization of the automation suite. With parallelization comes another difficult thing. Running the automation suite parallelly is not much cheaper. It requires a bigger infrastructure to run the suite. With all these things, we still have one solution that comes to mind: to reduce the cost and the running time of the automation suite, i.e., utilizing the docker technology, which will act as a different architecture but comes with a much cheaper or almost no cost. So, in today’s article, we will discuss how to achieve our goal of reducing the total turnaround time of the testing team with the help of automation testing utilizing technologies like Docker and Cucumber.

Kubernetes Ephemeral Containers: Enhancing Security and Streamlining Troubleshooting in Production Clusters

Aggregated on: 2024-12-30 13:25:40

Ephemeral containers in Kubernetes are a powerful feature that allows operators to debug and troubleshoot running Pods by creating short-lived containers within the same Pod. This is particularly helpful for issues that cannot be replicated in a separate environment. By using ephemeral containers, you can attach a container to a running Pod, inspect the file system, network settings, or running processes, and then discard the container without affecting the Pod’s primary containers. What Are Ephemeral Containers? Ephemeral containers are special containers that do not run as part of an application workload but are instead added to an existing Pod for the purpose of debugging. They share the same resources (network namespace, volumes, etc.) as the other containers in the Pod, making them ideal for real-time diagnosis. Once debugging is complete, the ephemeral container can be removed without needing to recreate the entire Pod.

Large models feature “Transformers,” while ETL relies on “Transform” processes — similar names representing vastly different paradigms. Some voices boldly predict: "ETL will be completely replaced in the future, as large models can handle all data!" Does this signal the end of the decades-old ETL framework underpinning data processing? Or is it merely a misunderstood prediction? Behind this conflict lies a deeper contemplation of technology's future.

Understanding the Chained Microservice Design Pattern

Aggregated on: 2024-12-25 13:25:37

The chained microservice design pattern is a common architectural approach that results in a single, consolidated response to a client request. Though it is widely used, many developers may employ it without fully realizing its implications. In this pattern, the request from the client is first handled by Service A, which then communicates with Service B, and subsequently, Service B may interact with Service C. Typically, this pattern relies on synchronous HTTP request-response communication between the services.

Transitioning From Postman to Insomnia

As we move away from using Postman, many of us are transitioning to Insomnia for API testing. In this article, I will share how I’ve set up Insomnia to streamline my own workflow. While Insomnia offers a wide range of capabilities beyond HTTP requests, I focus on using it solely for exercising HTTP requests. I hope this provides a useful reference as you configure your own setups. Just to clarify upfront, this isn't an installation guide. Getting Insomnia installed correctly can be a bit tricky, and I, too, have encountered some challenges during the installation and setup process.
