Quarkus vs RxJava: What are the differences?

Introduction Quarkus and RxJava are popular technologies in the Java ecosystem. While Quarkus is a Java framework designed for developing cloud-native microservices and serverless applications, RxJava is a library for composing asynchronous and event-based programs using observable sequences.

  1. Concurrency Model: Quarkus uses a traditional thread-based concurrency model where it utilizes native threads for handling requests and scaling applications. On the other hand, RxJava operates on a reactive programming model with an event-driven and non-blocking approach, allowing for better utilization of system resources and improved scalability.

  2. API Design: Quarkus focuses on building lightweight and fast microservices by offering a streamlined API designed for cloud-native development. In contrast, RxJava provides a rich set of operators and tools for composing complex asynchronous data streams, enabling developers to handle asynchronous operations easily.

  3. Error Handling: Quarkus emphasizes a more traditional error handling approach, where exceptions are thrown and caught within the application code. In comparison, RxJava utilizes a centralized error handling mechanism through observables, allowing developers to easily propagate and handle errors across asynchronous operations.

  4. Backpressure Handling: Quarkus does not inherently support backpressure handling, leading to potential issues when dealing with large volumes of data or requests. RxJava, however, provides built-in support for backpressure, enabling developers to control the flow of data and prevent overload in reactive systems.

  5. Compatibility: Quarkus is more focused on delivering optimized performance for cloud-native applications, which may require developers to adapt their coding practices and architecture. On the other hand, RxJava is a versatile library that can be used in various Java applications without significant changes, offering more flexibility in implementation.

  6. Community Support: Quarkus has a rapidly growing community of developers and contributors due to its modern approach to cloud-native development, providing active support and resources for developers. RxJava, with its established presence in the Java ecosystem, has a strong community backing and extensive documentation, making it easier for developers to find solutions and resources.

In Summary, Quarkus and RxJava differ in their concurrency model, API design, error handling mechanisms, backpressure support, compatibility with different applications, and the level of community support in the Java ecosystem.

Quarkus
Quarkus

A library for composing asynchronous and event-based programs by using observable sequences for the Java VM.

It tailors your application for GraalVM and HotSpot. Amazingly fast boot time, incredibly low RSS memory (not just heap size!) offering near instant scale up and high density memory utilization in container orchestration platforms like Kubernetes. We use a technique we call compile time boot.

What are some alternatives to RxJava, Quarkus?

MyBatis

MyBatis

It is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings. It eliminates almost all of the JDBC code and manual setting of parameters and retrieval of results. It can use simple XML or Annotations for configuration and map primitives, Map interfaces and Java POJOs (Plain Old Java Objects) to database records.

guava

guava

The Guava project contains several of Google's core libraries that we rely on in our Java-based projects: collections, caching, primitives support, concurrency libraries, common annotations, string processing, I/O, and so forth.

Thymeleaf

Thymeleaf

It is a modern server-side Java template engine for both web and standalone environments. It is aimed at creating elegant web code while adding powerful features and retaining prototyping abilities.

JSF

JSF

It is used for building component-based user interfaces for web applications and was formalized as a standard through the Java Community

JavaMelody

JavaMelody

It is used to monitor Java or Java EE application servers in QA and production environments. It is not a tool to simulate requests from users, it is a tool to measure and calculate statistics on real operation of an application depending on the usage of the application by users. It is mainly based on statistics of requests and on evolution charts.

MapStruct

MapStruct

It is a code generator that greatly simplifies the implementation of mappings between Java bean types based on a convention over configuration approach. The generated mapping code uses plain method invocations and thus is fast, type-safe and easy to understand.

Java 8

Java 8

It is a revolutionary release of the world’s no 1 development platform. It includes a huge upgrade to the Java programming model and a coordinated evolution of the JVM, Java language, and libraries. Java 8 includes features for productivity, ease of use, improved polyglot programming, security and improved performance.

Apache FreeMarker

Apache FreeMarker

It is a "template engine"; a generic tool to generate text output (anything from HTML to auto generated source code) based on templates. It's a Java package, a class library for Java programmers.

Jackson

Jackson

It is a suite of data-processing tools for Java (and the JVM platform), including the flagship streaming JSON parser / generator library, matching data-binding library (POJOs to and from JSON) and additional data format modules to process data encoded in Avro, BSON, CBOR, CSV, Smile, (Java) Properties, Protobuf, XML or YAML; and even the large set of data format modules to support data types of widely used data types such as Guava, Joda.

Project Reactor

Project Reactor

It is a fourth-generation Reactive library for building non-blocking applications on the JVM based on the Reactive Streams Specification. It is a fully non-blocking foundation with efficient demand management. It directly interacts with Java functional API, Completable Future, Stream and Duration.
