Spark Framework is a lightweight and expressive web framework for Java and Kotlin, designed to facilitate rapid development of web applications and microservices. It offers a simple and intuitive API that allows developers to handle HTTP requests and responses with minimal boilerplate code, making it ideal for building RESTful APIs and web applications efficiently. Key Features and Functionality: - Minimalistic and Lightweight: Spark Framework is designed to be extremely lightweight, offering just the core functionality needed to handle HTTP requests and responses. There are no unnecessary features or configurations, so developers can focus on building the application without distractions. - Fluent API: Spark Framework uses a fluent API, which makes it easy to define routes, handle HTTP methods, and return responses. The code is clean, intuitive, and easy to read. It’s a great framework for developers who appreciate simplicity and want to get their application running quickly. - REST API Support: Spark Framework is built with RESTful web services in mind, making it easy to create and manage REST APIs. It has built-in support for routing HTTP methods (GET, POST, PUT, DELETE, etc.) and returning responses in various formats such as JSON, HTML, or plain text. - No Configuration Required: One of the standout features of Spark Framework is that it doesn’t require any configuration files, which is a stark contrast to larger frameworks like Spring. You simply create a Java file, add the necessary routes, and start the server — that’s it! This ease of use makes it great for rapid prototyping and small-scale applications. Primary Value and Problem Solved: Spark Framework addresses the need for a straightforward and efficient tool for developing web applications and microservices in Java and Kotlin. By eliminating complex configurations and providing a clean, expressive API, it enables developers to focus on writing application logic rather than dealing with the intricacies of the framework. This approach significantly reduces development time and effort, making Spark Framework an excellent choice for projects that require rapid development and deployment. * * * Seller [The Apache Software Foundation](https://www.g2.com/sellers/the-apache-software-foundation) Discussions [Spark Community](https://www.g2.com/products/apache-spark/discuss) Solution Type Best-of-Breed Overview by Chinmay Deshpande (Big data developer | Hadoop | Hive | Sqoop | Hbase | SQL | Apache Spark | Pyspark | Scala | Python) Show More ## Value at a Glance Averages based on real user reviews. ### Perceived Cost $$$$$ [ View More Pricing Information ](https://www.g2.com/products/apache-spark/pricing) ## Top-Rated Alternatives [ ![spring.io](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "spring.io") spring.io 4.5/5(320) ](https://www.g2.com/products/spring-io/reviews) [ ![Grails](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Grails") Grails 3.6/5(33) ](https://www.g2.com/products/grails/reviews) [ ![Vaadin](/assets/transparent-ad5be28fbcd25b7b08d2cebe1d957125437fb5407d75ee717965ad22c8808791.gif "Vaadin") Vaadin 4.1/5(36) ](https://www.g2.com/products/vaadin/reviews) [ View All Alternatives ](https://www.g2.com/products/apache-spark/competitors/alternatives) ## User Insights Average based on 54 real user reviews.

Open source application written in Java (therefore platform independent) that utilizes the Jabber/XMPP protocol, therefore you can have multiple clients being able to connect to the server (along with being able to set the "priority", assuming other client has the functionality) for where new messages/notifications would be sent / transferred to via FastPath support. Review collected by and hosted on G2.com. What do you dislike about Spark? The client itself seemed to have a bit of limited functionality in comparison to other clients (such as Adium) in terms of logging (locally). I would have simply used Adium solely when connecting to the Jabber server, other than it has \*limited\* fastpath support -- you could definitely transfer a live chat over to another tech (such as yourself, where it'd go to Adium based on the priority) after accepting via Spark. Transferring chats over to Adium was definitely easier to communicate and also have local logging support. Review collected by and hosted on G2.com. Recommendations to others considering Spark: It depends on what your purpose is for wanting to use this product (along with if they've improved / fixed things since I had last used it). If it's for live customer support, ZenDesk is probably the better solution. If it's just for internal communication, Slack is by far one of the best products/applications to use - otherwise, I'd suggest a different client all together (such as Adium for OS X, Pidgin for Linux or Windows) just to connect to the Jabber/XMPP server. Review collected by and hosted on G2.com. What problems is Spark solving and how is that benefiting you? We aren't using the product/software anymore, but it provided 24/7/365 live technical support for customers. That system (along with many other internal projects/systems) were migrated to 3rd party vendors where their products are far superior. Review collected by and hosted on G2.com.
