How To Integrate NCache With JPA Hibernate for Caching in Spring Boot Applications

Aggregated on: 2024-02-20 15:32:12

What Is JPA Hibernate? Hibernate is one of the most popular Object Relational Mapper (ORM) libraries for Java and Spring applications. It helps developers connect to and work with relational databases from Java applications without having to write SQL queries. The library implements the JPA (Java Persistence API) specification and provides several additional features that help develop persistence in applications faster and easier. Caching in JPA Hibernate One of the cool features supported by Hibernate is caching. Hibernate supports two levels of caching — L1 and L2. L1 cache is enabled by default and works within an application scope, so it cannot be shared across multiple threads. For example, if you have a scaled microservice application that reads and writes to a table in a relational database setup, this L1 cache is maintained individually within each of these containers where the microservice is running.

Data Mesh: A Paradigm Shift in Data Management

Aggregated on: 2024-02-20 15:02:12

In this article, I’m going to share my thoughts about Data Mesh, the concept I came across a few years back. It was first introduced in 2018 at a conference called "Building Scalable and Reliable Data Products" by Zhamak Dehghani. A concept based on Domain Driven Design from the Book “Domain-Driven Design: Tackling Complexity in the Heart of Software” by Eric Evans. Data mesh is a new technology that could provide a framework for managing distributed data ecosystems more effectively by treating data as a product and empowering teams to take ownership of their data, while also enabling effective communication to interconnect distributed data residing in different locations. And by effective communication, I meant building a solid linkage between the data domains for proper data availability. I’m into the Analytics data world, currently, using Data Lake and its predecessor Data Warehouse. These are today’s data platform architectures to support businesses with Data Science, Data Analytics, and Business Intelligence solutions respectively. Let me first begin with what Analytical Data means, unlike Operational/ Transaction data, Analytics data is an aggregated view of the business data over time, modeled using business rules to provide insights and patterns to make business decisions. However, useful and quality insights and opportunities for businesses can be achieved only by using the data efficiently. The world today is generating a massive amount of data and with the rise of cloud computing, microservices architecture, and other modern technologies, data is becoming more complex to be handled by a single central data team as well as increasingly distributed across different systems and teams creating more silos, which is making it difficult to be managed and integrated as efficiently as possible. This is where Data Mesh is gaining popularity in the data management and data engineering community.

In recent years, Domain Driven Design (DDD) has become a buzzword in the software development community, often surrounded by discussions focused on its tactical patterns: entities, value objects, repositories, services, aggregates, and more. This mainstream portrayal of DDD has, unfortunately, done a disservice to the software community. The emphasis on these complex patterns has led many to view DDD as overly complicated and inaccessible, particularly for projects that appear to have simpler domains. The question arises: why entangle your project in the web of DDD's tactical patterns if they seem unnecessary? The Misguided Focus and Its Consequences The vast majority of content and discussions available online revolve around DDD's tactical aspects, obscuring its true essence and benefits. This skewed focus has made it easy to lose sight of what DDD fundamentally aims to achieve: the strategic advantage of clearly defined boundaries within your domain, encapsulated by the concept of a bounded context. Unfortunately, for many newcomers to DDD, the bounded context—the cornerstone of DDD's strategic patterns — is not what they first encounter. Instead, they are introduced to DDD through tutorials or sample applications that dive straight into its tactical patterns without establishing a foundational understanding of the domain itself.

Scaling Redis Without Clustering

Aggregated on: 2024-02-15 20:02:09

Redis is a popular in-memory data store known for its speed and flexibility. It operates efficiently when a particular workload's memory and computational demands can be managed within a single node. However, scaling beyond a single node often leads to the consideration of the Redis Cluster. There's a common assumption that transitioning to the Redis Cluster is straightforward and existing applications will behave the same, but that's not the case in reality. While Redis Cluster addresses certain scaling issues, it also brings significant complexities. This post will discuss the limitations of scaling with Redis Cluster, and introduce some simpler alternatives that may meet many organizations' needs. What Is the Redis Cluster? Redis Cluster is a distributed implementation that allows you to share your data across multiple primary Redis instances automatically and thus scale horizontally. In a Redis Cluster setup, the keyspace is split into 16384 hash slots (read more here), effectively setting an upper limit for the cluster size of 16384 master instances. However, in practice, the suggested maximum size is on the order of ~1000 master instances. Each master instance within the cluster manages a specific subset of these 16,384 hash slots. To ensure high availability, each primary instance can be paired with one or more replica instances. This approach, involving data sharding across multiple instances for scalability and replication for redundancy, is a common pattern in many distributed data storage systems. A cluster having three primary Redis instances, with each primary instance having one replica, is shown below:

Aggregated on: 2024-02-15 19:47:09

In the dynamic world of cloud-native technologies, monitoring and observability have become indispensable. Kubernetes, the de-facto orchestration platform, offers scalability and agility. However, managing its health and performance efficiently necessitates a robust monitoring solution. Prometheus, a powerful open-source monitoring system, emerges as a perfect fit for this role, especially when integrated with Kubernetes. This guide outlines a strategic approach to deploying Prometheus in a Kubernetes cluster, leveraging helm for installation, setting up an ingress nginx controller with metrics scraping enabled, and configuring Prometheus alerts to monitor and act upon specific incidents, such as detecting ingress URLs that return 500 errors. Prometheus Prometheus excels at providing actionable insights into the health and performance of applications and infrastructure. By collecting and analyzing metrics in real-time, it enables teams to proactively identify and resolve issues before they impact users. For instance, Prometheus can be configured to monitor system resources like CPU, memory usage, and response times, alerting teams to anomalies or thresholds breaches through its powerful alerting rules engine, Alertmanager.

10 Bold Predictions for AI in 2024

Aggregated on: 2024-02-15 19:17:09

With 2023 in the rearview mirror, it's fair to say that OpenAI's release of ChatGPT just over a year ago threw the tech industry into an excited, manic state. Companies like Microsoft and Google have thrown tremendous resources at AI in order to try to catch up, and VCs have tripped all over themselves to fund companies doing the same. With such a tremendous pace of innovation, it can be difficult to spot what's coming next, but we can try to take clues from AI's evolution so far to predict where it's headed. Here, we present 10 bold predictions laying out how emerging trends in AI development are likely to play out in 2024 and beyond. 1. Personal AI Trained on Your Data Becomes the Next Big Thing While some consumers were awed by the introduction of ChatGPT, perhaps many more picked it up, played with it, and moved on with their lives. But in 2024, the former audience is likely to re-engage with the technology, as the trend towards personal AI will revolutionize user interactions with technology. These AI systems, trained on individual user data, offer highly personalized experiences and insights. For example, Google Gemini now integrates with users' Google Workspace data, enabling it to leverage everything it knows about their calendars, documents, location, chats and more. Meanwhile, companies like Apple and Samsung are likely to emphasize on-device AI as a key feature, prioritizing privacy and immediacy. It's not hard to imagine a personal AI with access to all of your data acting as a relationship, education, and career coach, becoming a more integral, personalized part of everyday life.

By utilizing generative AI, businesses can streamline and enhance various processes, resulting in increased productivity, efficiency, and innovation. One of the key advantages of generative AI in business automation is its ability to speed up content creation. With generative AI, businesses can produce high-quality writing in seconds, reducing the time and effort required to develop marketing copy, technical materials, or any other written materials. Generative AI can also assist in software development, generating code that is largely correct and instantaneous. This allows IT and software organizations to accelerate their development cycle, saving time and resources.

The Power of Refactoring: Extracting Interfaces for Flexible Code

Aggregated on: 2024-02-15 18:02:09

In the dynamic landscape of software development, where change is the only constant, the ability to adapt quickly is paramount. This adaptability hinges on the flexibility of our codebases, which can be significantly enhanced through the judicious use of refactoring techniques. Among these techniques, the extraction of interfaces is a powerful tool for architecting robust and agile systems. In this article, we’ll explore the significance of interface extraction in refactoring, using a practical example from e-commerce development to illustrate its transformative potential. The Essence of Refactoring Creating software that gracefully accommodates change is a hallmark of practical software engineering. Yet, striking the balance between adaptability and complexity can be challenging. It's tempting to preemptively introduce numerous layers and interfaces in anticipation of future requirements, but this approach can often backfire. As the adage goes, "We might need it in the future," but over-engineering for hypothetical scenarios can lead to unnecessary complexity and maintenance overhead.

The Future of AI Chips: Leaders, Dark Horses and Rising Stars

Aggregated on: 2024-02-15 17:17:09

The interest and investment in AI is skyrocketing, and generative AI is fueling it. Over one-third of CxOs have reportedly already embraced GenAI in their operations, with nearly half preparing to invest in it. What’s powering it all, AI chips used to receive less attention. Up to the moment, OpenAI’s Sam Altman claimed he wants to raise up to $7 trillion for a “wildly ambitious” tech project to boost the world’s chip capacity. Geopolitics and sensationalism aside, however, keeping an eye on AI chips means being aware of today’s blockers and tomorrow’s opportunities.

The Noticeable Shift in SIEM Data Sources

Aggregated on: 2024-02-15 16:17:09

SIEM solutions didn't work perfectly well when they were first introduced in the early 2000s, partly because of their architecture and functionality at the time but also due to the faults in the data and data sources that were fed into them. During this period, data inputs were often rudimentary, lacked scalability, and necessitated extensive manual intervention across operational phases. Three of those data sources stood out.

Be Punctual! Avoiding Kotlin’s lateinit In Spring Boot Testing

Aggregated on: 2024-02-15 16:02:09

A sign of a good understanding of a programming language is not whether one is simply knowledgeable about the language’s functionality, but why such functionality exists. Without knowing this “why," the developer runs the risk of using functionality in situations where its use might not be ideal - or even should be avoided in its entirety! The case in point for this article is the lateinit keyword in Kotlin. Its presence in the programming language is more or less a way to resolve what would otherwise be contradictory goals for Kotlin: Maintain compatibility with existing Java code and make it easy to transcribe from Java to Kotlin. If Kotlin were too dissimilar to Java - and if the interaction between Kotlin and Java code bases were too much of a hassle - then adoption of the language might have never taken off. Prevent developers from declaring class members without explicitly declaring their value, either directly or via constructors. In Java, doing so will assign a default value, and this leaves non-primitives - which are assigned a null value - at the risk of provoking a NullPointerException if they are accessed without a value being provided beforehand. The problem here is this: what happens when it’s impossible to declare a class field’s value immediately? Take, for example, the extension model in the JUnit 5 testing framework. Extensions are a tool for creating reusable code that conducts setup and cleanup actions before and after the execution of each or all tests. Below is an example of an extension whose purpose is to clear out all designated database tables after the execution of each test via a Spring bean that serves as the database interface:
