Apache Iceberg Table Management

Aggregated on: 2024-07-30 18:23:37

1. What Are Iceberg and Table Layout for Iceberg? Apache Iceberg is a high-performance table format for large analytic datasets. It's designed to handle petabyte-scale data lakes with the reliability and efficiency needed for data analytics and big data workflows. Iceberg tables organize data into a consistent format that simplifies querying, updating, and managing data at scale. One of the main advantages of Iceberg table format is schema evolution, which allows updating the table schema without re-writing the data. However, all these advantages come at the cost of maintaining table metadata disjoint from data in metadata files which are updated for each table ops in a transaction while maintaining concurrency. A typical Iceberg table layout has: Manifest files: Store metadata about data files in the table, including their locations, sizes, and statistics. Snapshot files: Represent the state of the table at a given point in time. Each snapshot includes references to manifest files and data files. Data files: Contain the actual data in the table, typically stored in columnar formats like Parquet or ORC. Metadata files: Store global metadata about the table, such as schema, partitioning information, and properties. CRUD operations on table leads to generation of multiple snapshot files, manifest files, data files etc which can consume storage making the table operations inefficient.

How Kubernetes Changed the Networking Model and What Developers Should Know about eBPF and Cilium

Aggregated on: 2024-07-30 14:38:34

Enterprise networking is a radically different discipline in today’s microservices, containers, and Kubernetes paradigm than what it used to be in the old three-tier architecture world. Containers broke traditional networking models, and in this networking rethink for the distributed computing era, a lot has happened in a very short period of time. In this exclusive interview, Nicolas Vibert — senior technical engineer at Isovalent — traces this evolution and explains how open-source projects like eBPF and Cilium are continuing to drive advanced networking use cases for the modern cloud era. Q: How Did Kubernetes Change the Networking Model? What’s Fundamentally Different About Networking in K8s/Cloud-Native Environments From Prior Enterprise Architectures? A: In many ways, Kubernetes networking is similar to our traditional networking. Regardless of the underlying computing platform, you need your network to support the needs of your business and the applications they rely upon. The requirements are the same whether you are running apps on bare metal servers, virtual machines, or on Kubernetes: you need to connect applications, you need to make them accessible to end users, you need to secure access to them, and adhere to regulatory requirements, etc…

Why Do We Need to Keep Our Builds Green?

Aggregated on: 2024-07-30 14:23:34

The Trivial Answer Most engineers know that we must have green builds because a red build indicates some kind of issue. Either a test did not pass, or some kind of tool found a vulnerability, or we managed to push our code when it couldn’t even compile. Either way, it is bad. You might have noticed that this article is far from over, so there must be more to this. You are right! What Does Green Mean Exactly? We have already discussed that red means something wrong, but can we say that green is the opposite? Does it guarantee that everything is working great, meets the requirements, and is ready to deploy? As usual, it depends.

How To Achieve High GC Throughput

Aggregated on: 2024-07-29 22:08:34

In this post, let’s explore a key performance metric studied during garbage collection analysis: "GC throughput." We’ll understand what it means, its significance in Java applications, and how it impacts overall performance. Additionally, we’ll delve into actionable strategies to improve GC throughput, unlocking its benefits for modern software development. What Is Garbage Collection Throughput? Whenever an automatic garbage collection event runs, it pauses the application to identify unreferenced objects from memory and evict them. During that pause period, no customer transactions will be processed. Garbage collection throughput indicates what percentage of the application’s time is spent in processing customer transactions and what percentage of time is spent in the garbage collection activities. For example, if someone says his application’s GC throughput is 98%, it means his application spends 98% of its time processing customer transactions and the remaining 2% of the time processing Garbage Collection activities.

Application-Level Tracing: The Good, the Bad, and the Alternative

Aggregated on: 2024-07-29 16:23:33

The Sailormen's Legacy: A "Trace" of the Past By the late 16th century, sailors were measuring speed with a chip log — a method crucial for navigation. Knots were tied at regular intervals in a rope, with one end attached to a pie-slice-shaped piece of wood ("chip") and flung behind the vessel. The rope played freely as the ship traveled for a fixed amount of time, which was measured using an hourglass. The number of knots that passed over the stern was counted to determine the ship's speed, with one knot equaling one nautical mile an hour. Thus, a ship going at 15 knots could traverse 15 nautical miles in an hour. Records of these measurements were kept in a logbook, which was used to calculate the ship's speed over a given period. This logbook was also used to record the ship's course, weather conditions, and other relevant information. The term "log" was derived from this practice, and it has since been used in various contexts to refer to a record of events or activities. In software engineering, the principle of logging has been refined and expanded to include “traces." In software development, tracing represents a dynamic method of observing, debugging, and recording activities within an application, providing a more detailed, sometimes interactive, insight than traditional logging.

Creating a Cohesive User Experience Using HSL Colors in CSS

Aggregated on: 2024-07-29 15:23:33

We all know what importance colors hold in anything, whether it’s a website layout, image, video, or any other graphical element. In essence, color is a subjective experience that results from the interaction between light, the eye, and the brain. Adding colors to the website gives a new life to the whole layout and graphical elements. Nobody likes to visit web pages with white, black, and gray colors on them. Colors make the elements look more realistic and catchy to the human eye. Not just theoretically, psychology also comes into play when we use colors on websites. It has been scientifically proven that a specific set of colors triggers particular emotions in the human brain, such as autumn colors like orange and yellow representing joy or happiness, red color to festive seasons, and blue viewed as calm and trustworthy. Besides, you must have noticed that many food companies often use red and yellow on their websites, pharmaceutical companies tend to use green on their sites, fitness companies sometimes use orange, and so on.

How To Write End-To-End Tests Using Cypress App Actions

Aggregated on: 2024-07-29 13:23:33

When I started writing tests with Cypress, I was always going to use the user interface to interact and change the application's state when running tests. This could be beneficial since it gives you the same behavior as an end-user interacting with the application. But this is only sometimes the case. Sometimes, you only need to manipulate the state in your application without using the UI. You might have already tested it in a different test case and only need the state to test the next feature. In this case, using the UI to interact with the application could be redundant and time-consuming.

Introduction to Polymorphism With Database Engines in NoSQL Using Jakarta NoSQL

Aggregated on: 2024-07-26 18:38:32

Polymorphism, a fundamental concept in object-oriented programming, allows objects of different types to be treated as instances of a common superclass. This flexibility is essential for creating systems that can be easily extended and maintained. While traditional SQL databases in combination with Jakarta Persistence (JPA) can handle polymorphic data, NoSQL databases offer distinct advantages. Unlike SQL databases, which require strict schema definitions, NoSQL databases take a schema-less approach, inherently supporting dynamic and flexible data structures. This flexibility becomes especially appealing when integrated with Jakarta NoSQL, a tool that provides robust support for defining and managing polymorphic fields through custom converters. In many enterprise applications, there is a common need to manage different types of data objects. For example, an e-commerce platform may handle various payment methods such as credit cards, digital wallets, and bank transfers, each with specific attributes. Similarly, asset management systems in large corporations deal with different types of assets like real estate, machinery, and intellectual property, each with unique properties. Healthcare systems must accommodate various data types, from personal information to medical records and test results. Utilizing NoSQL databases with polymorphic fields can store and manage these diverse data types cohesively. The schema-less nature of NoSQL databases also makes it easier to adapt to changing requirements than relational databases.

How To Secure Your Angular Apps: End-To-End Encryption of API Calls

Aggregated on: 2024-07-26 16:38:32

When it comes to secure web applications, we must keep sensitive data secure during the communication period. Sadly, while HTTPS encrypts data as it moves from point A to point B, the information is still exposed in a browser's network tab and can leak out this way. In this post, I will give you an example of implementing end-to-end encryption of API calls in your secure web app built with Angular. Encryption Workflow Weak protections have traditionally been obfuscation with Base64 encoding or custom schemes. Public key cryptography (PKC) is considered a modern solution to be more secure. It uses a key pair one public key for encryption, and the other private key for decryption. A public key is distributed and a private key is kept on the server.

OpenTelemetry: Unifying Application and Infrastructure Observability

Aggregated on: 2024-07-25 17:08:31

In this insightful Q&A, Goutham Veeramachaneni, a long-time Prometheus maintainer and Product Manager at Grafana Labs, shares his unique perspective on the transformative impact of OpenTelemetry (OTel) in the observability landscape. Veeramachaneni discusses how OTel is standardizing telemetry data and inspiring new open-source data collectors and workflows that bridge the gap between application and infrastructure monitoring. He offers valuable insights into the evolving ecosystem, the challenges ahead, and the exciting possibilities for developers in composing more effective telemetry data pipelines. Q: As a Long-Time Prometheus Maintainer, What’s Your Take on the Overall Impact That OpenTelemetry Has Had on the Market? A: It’s given developers and platform teams much greater ownership of their data. It’s given them flexibility and freedom that they didn’t have before. Previously, with no universal open standard for telemetry data, the proprietary vendor mousetraps were designed to make it super difficult to migrate to other solutions, which was insane. These vendors didn’t have a lot of incentive to innovate or compete, because they had instrumented such effective mousetraps to lock users in. They spoke their protocols and collected their metrics, and there was no standardization. OpenTelemetry already has forced the entire market to standardize on the OTLP protocol and its ecosystem of SDKs and APIs. That has taken the power away from vendors and created a standard that is dynamic and open and where everyone collaborates — which is driving a ton of innovation.

Developing Event-Driven, Auto-Compensating Saga Transactions For Microservices

Aggregated on: 2024-07-25 16:38:31

Over the past decade, I have presented many times and written numerous blogs and source code on sagas and event-driven microservices. In those blogs, I’ve discussed the need for sagas in microservices architectures, the preferred and increased use of event-driven patterns and communication for microservices, and the difficulties in implementing sagas, particularly around developing saga participant code for compensating transactions. These are addressed in the product solution I will describe, including an example source code here, and soon, an update of the beta version of the saga workshop showing the same. The features are in the Oracle Database Free Docker container and soon in the Oracle Autonomous Database. Part of what makes the new Oracle Saga Framework so powerful is its combined usage of other features in the Oracle Database including the TxEventQ transactional messaging system and reservation-less locking; therefore, I will describe them and how they contribute to the overall comprehensive solution as well.

Pilot VPC and Advanced NAT: Securely Connect Overlapping Networks to AWS VPC

Aggregated on: 2024-07-25 15:08:31

In today's dynamic business environment, cloud computing has become a crucial enabler, offering enterprises unmatched scalability, flexibility, and cost-efficiency. Amazon Web Services (AWS), a leading cloud service provider, has transformed how organizations manage their IT infrastructures and applications. With AWS Virtual Private Clouds (VPCs), businesses can establish secure, isolated environments within the cloud, replicating the capabilities of traditional on-premises networks. However, despite the clear benefits of cloud adoption, bridging the gap between on-premises networks and AWS VPCs can be challenging, particularly when dealing with overlapping IP addresses. Situations often arise where on-premises networks and AWS cloud environments unintentionally use the same private IP addresses, obstructing communication and data exchange across the VPN tunnel. This article addresses this specific issue and explores an innovative solution for establishing secure connectivity between overlapping on-premises networks and AWS VPCs. Leveraging AWS site-to-site VPN, the traditional method for connecting on-premises environments and VPCs, enterprises frequently face obstacles when managing conflicting IP addresses. Mergers, acquisitions, and other networking complexities further complicate the situation, making straightforward resolution difficult.

Optimizing Search Precision With Self-Querying Retrieval (SQR) and Langchain

Aggregated on: 2024-07-25 13:08:31

What Is Self-Querying Retrieval? Self-querying retrieval (SQR) is a method ensuring that LLMs are at the core of understanding the user's intent against a document collection. Key ideas include: Document representation: Word embedding provides a numerical vector for every document. This helps in fast comparison between the documents. User query: The user submits a natural language query expressing their need for information. LLM-driven retrieval: The query and the document representations are fed into the LLM, which then retrieves documents that maximize the user's intent. Refine and repeat: The user is now able to refine his query or ask follow-up questions to narrow the search based on the retrieved documents. Why Self-Querying Retrieval? Traditional retrieval systems usually require complex query languages or predefined search facets. However, self-querying retrieval would provide a much more natural and user-friendly approach. Here is why:

Key Strategies on How to Advance Your Digital Tech Career

Aggregated on: 2024-07-24 23:08:31

The digital technology market is highly saturated and competitive, and to survive there, you need to succeed. Tech employers constantly seek IT professionals with the latest industry knowledge and expertise due to interconnected reasons: digital technology companies compete in international markets with each other, thus they need to be adaptive and constantly introduce new products and features to remain competitive. For every person working in the IT sector, it’s crucial to be up-to-date with the latest and most influential innovations and trends in their industry, read professional literature, and constantly develop new skills. What main skills have the most value in the digital tech market? What is the perfect ratio between hard and soft skills? Hard Skills vs Soft Skills Each employee's role is specific to different areas of digital technology, and it is difficult to determine the exact ideal balance between hard and soft skills. However, on average, I would say that for technical roles, the percentage of hard skills is approximately 60-70 percent and 30-40 percent for soft skills. But for managerial roles, on the contrary, hard skills should be slightly less than 50 percent. Among the most important soft skills are clear communication, adaptability, critical and strategic thinking, and time management. Therefore, if your goal is to advance your career in leadership positions, it’s better to concentrate on polishing your soft skills, or, alternatively, try to achieve an equal balance of hard and soft skills through continuous development in both areas which can lead to a greater career success.

Automated alert systems and authentication measures are now standard, but these relatively simple, rules-based solutions are still imperfect. The growing field of behavioral biometrics offers a more reliable alternative. Higher Detection Accuracy Behavior biometrics’ accuracy is its primary advantage over conventional fraud detection. Researchers have developed systems capable of identifying fraud 95.5% of the time by tracking keystrokes alone. Such precision is difficult with a rules-based system, especially when it comes to unknown attack patterns.

Snowflake Integration Patterns: Apache Kafka vs. Zero ETL and Reverse ETL

Aggregated on: 2024-07-24 20:38:31

Snowflake is a leading cloud-native data warehouse. Integration patterns include batch data integration, Zero ETL, and near real-time data ingestion with Apache Kafka. This blog post explores the different approaches and discovers their trade-offs. Following industry recommendations, it is suggested to avoid anti-patterns like Reverse ETL and instead use data streaming to enhance the flexibility, scalability, and maintainability of enterprise architecture. Blog Series: Snowflake and Apache Kafka Snowflake is a leading cloud-native data warehouse. Its usability and scalability made it a prevalent data platform in thousands of companies. This blog series explores different data integration and ingestion options, including traditional ETL/iPaaS and data streaming with Apache Kafka. The discussion covers why point-to-point Zero-ETL is only a short-term win, why Reverse ETL is an anti-pattern for real-time use cases, and when a Kappa Architecture and shifting data processing “to the left” into the streaming layer helps to build transactional and analytical real-time and batch use cases in a reliable and cost-efficient way.

Democratizing Data With Graph RAG: What It Is, What It Can Do, How To Evaluate It

Aggregated on: 2024-07-24 18:38:31

Are you interested in making your data more accessible? A rhetorical question indeed. Even if you are well-versed in dark arts such as databases, data modeling, data science, and information retrieval, why would you not want to make data more accessible even to non-experts? Contrary to popular belief, data collection started in the analog age. Accessing analog data imposes severe limitations compared to what is possible with digital data. However, even with digital data, data democratization is not an easy feat for any organization.

Aggregated on: 2024-07-24 17:08:31

Imagine inheriting a codebase where classes are clean and concise, and developers don't have to worry about boilerplate code because they can get automatically generated getters, setters, constructors, and even builder patterns. Meet Lombok, a library used for accelerating development through "cleaning" boilerplate code and injecting it automatically during compile time. But, is Lombok a hero or a villain in disguise? Let's explore the widespread perceived benefits and potential drawbacks of its adoption in enterprise Java solutions.

Effortless API Mocking With Playwright

Aggregated on: 2024-07-24 17:08:31

Automated testing of web applications often requires interaction with external APIs. However, relying on actual API responses can introduce variables beyond your control, such as network issues or server downtime. This is where API mocking comes in. Mocking allows you to simulate API responses, making your tests more reliable and faster. In this article, we’ll explore how to mock APIs using Playwright with TypeScript. Mocking APIs in Playwright Playwright provides a way to intercept network requests and mock responses using the route method. Let’s walk through an example where we mock an API response.

My Shortcut of Choice: Reading the Source Code

Aggregated on: 2024-07-24 16:38:31

There is a great post post on c2.com. c2.com is one of those golden blogs of the past just like codinghorror and Joel on software. You might have stumbled upon them before especially if you have been around for a long time. In the past, it was the norm to encourage individuals to read the source code and be able to figure out how things work. I see a trend against it from time to time including ranting on open source software and its documentation, which feels weird since having the source code available is essentially the ultimate form of documentation.

Comprehensive Guide To Static Testing: Tools, Challenges, and Benefits

Aggregated on: 2024-07-24 15:08:31

To create high-quality software, it’s essential to thoroughly test applications before releasing them to customers. There are numerous methods available to rigorously analyze the software you’ve developed. Static testing is a valuable software development technique that focuses on preventing defects early on, without executing the code. By performing static tests in the early stages of development, you can avoid potential defects and improve code quality. What Is Static Testing? Static testing is a type of testing performed on software without actually running the code. During the testing process, we review and verify the product and its supporting documentation. In contrast, dynamic testing is the testing of software while the code is executing.
