Reactive Database Access on the JVM

Aggregated on: 2023-07-13 16:01:10

A couple of years ago, Reactive Programming was all the rage, but it had one big issue: reactive stopped as soon as you access a SQL database. You had a nice reactive chain up to the database, defeating the whole purpose. Given the prevalence of SQL databases in existing and new apps, one couldn't enjoy the full benefits of Reactive Programming but still pay the full price of complexity. Since then, the landscape has changed tremendously. Most importantly, it offers many reactive drivers over popular databases: PostgreSQL, MariaDB and MySQL, Microsoft SQL Server, Oracle, you name it! Even better, some frameworks provide a reactive API over them.

Five Critical Questions To Inform an IPaaS Selection for SMBs

Aggregated on: 2023-07-13 15:01:09

For a long time, only large, well-funded businesses made data analytics the centerpiece of their operations. That's because standing up an analytics department was costly, and positive results were far from guaranteed. In fact, some estimates indicate that only a paltry 20% of analytics-driven insights yielded meaningful business outcomes as of 2022. At scale, though, that's not a major problem. After all, a single well-placed insight within that 20% could mean that a big analytics program had paid for itself. However, for a small business, those odds don't always justify spending scarce resources on an analytics program. That was, of course, until a panoply of plug-and-play SaaS analytics solutions appeared that took much of the heavy lifting out of mining business data for insights. As a result, some 67% of small businesses now spend at least $10,000 per year on analytics operations.

After research and comparison, they came to the Apache Doris community, and we help them build a Doris-based data architecture.

Building for Failure: Best Practices for Easy Production Debugging

Aggregated on: 2023-07-12 16:16:09

Quite a few years ago, I was maintaining a database-driven system and ran into a weird production bug. The column I was reading from had a null value, but this wasn’t allowed in the code, and there was no place where that value could have been null. The database was corrupt in a bad way, and we didn’t have anything to go on. Yes, there were logs. But due to privacy concerns, you can’t log everything. Even if we could, how would we know what to look for? Programs fail. That’s inevitable. We strive to reduce failures, but failure will happen. We also have another effort, and it gets less attention: failure analysis. There are some best practices and common approaches, most famously logging. I’ve often said before that logs are pre-cognitive debugging, but how do we create an application that’s easier to debug?

Rust and Sustainability: Programming for a Greener Future

Aggregated on: 2023-07-11 16:46:08

In an era where sustainable practices are more important than ever, the selection of programming languages has shifted to include factors such as environmental impact alongside performance, ease of use, and scalability. Rust has emerged as a standout choice in this context, driving us toward a greener future in programming. This article will delve into Rust's potential for a sustainable future, the hurdles to its adoption, and strategies for a successful transition to Rust. Why Choose Rust for Sustainability? Rust's promise in the landscape of sustainable coding springs from its unique attributes. Its low-level functionality allows it to operate close to system hardware without needing a garbage collector. This lack of overhead reduces the computational power and energy needed to run applications, promoting efficiency. Rust's inherent support for concurrent programming and absence of a global garbage collector optimizes multi-core processor usage, leading to better resource management. It also guarantees memory safety without garbage collection, lessening the likelihood of resource-wasting memory leaks. Moreover, Rust offers predictable performance characteristics, minimizing unexpected excessive use of computational resources.

(Hopefully) The Final Article About Equals and HashCode for JPA Entities With DB-Generated IDs

Aggregated on: 2023-07-11 16:46:08

In this article, we’ll explore the proper implementation of the equals() and hashCode() methods for JPA entities. While you can find a lot of implementations on the internet, it's crucial to understand the reasoning behind the chosen implementations to avoid potential issues. By reading the entire article, you will: Gain insights about default equals() and hashCode() implementations; Discover issues you might encounter using common equals() and hashCode() implementations found on the internet; Learn a lot of interesting things about proxies in Hibernate. However, if you're short on time, you can skip to the end, copy the proper equals() and hashCode() methods, and paste them into your code :). Should We Override Equals and HashCode at All? Let's begin with a simple example. We have an online school application. Now, we need to create a REST endpoint that retrieves all students whose names start with specific letters and have an average grade lower than a certain value. Luckily, we already have a service with methods that can help us complete this task. Java @Getter @Setter @Entity @Table(name = "student") public class Student { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id", nullable = false) private Long id; @Column(name = "name") private String name; @Column(name = "average_grade") private Short averageGrade; } Java { Set findByAverageGradeLessThan(Short averageGrade); Set findByNameStartsWithIgnoreCase(String name); }" data-lang="text/x-java"> public interface StudentRepository extends JpaRepository<Student, Long> { Set<Student> findByAverageGradeLessThan(Short averageGrade); Set<Student> findByNameStartsWithIgnoreCase(String name); } Java getStudentsWithNameStartsWith(String letter) { return studentRepository.findByNameStartsWithIgnoreCase(letter); } @Transactional public Set getStudentsWithAverageGradeLessThan(Short averageGrade) { return studentRepository.findByAverageGradeLessThan(averageGrade); } } " data-lang="text/x-java"> @Service public class StudentService { private final StudentRepository studentRepository; public StudentService(StudentRepository studentRepository) { this.studentRepository = studentRepository; } @Transactional public Set<Student> getStudentsWithNameStartsWith(String letter) { return studentRepository.findByNameStartsWithIgnoreCase(letter); } @Transactional public Set<Student> getStudentsWithAverageGradeLessThan(Short averageGrade) { return studentRepository.findByAverageGradeLessThan(averageGrade); } } So, the controller with the corresponding REST endpoint will look like this:
