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.

AK Abhishek K. Technical Lead Information Technology and Services Enterprise (\> 1000 emp.) 8/14/2025 "Apache Spark: Fast, Capable, But Needs Care to Run Well" 4.5/5 What do you like best about Spark? Spark is great for working with really large amounts of data. It can handle both batch jobs and streaming data, and it works with different file types and data sources. It’s much faster than older systems because it can process data in memory. I also like that it has built-in tools for data queries, streaming, and even machine learning, so you can do a lot without switching platforms. Review collected by and hosted on G2.com. What do you dislike about Spark? Spark is not as “easy” as people think. If it’s not set up or tuned properly, it can run slowly or cost a lot to operate. One small mistake in how you write or run a job can slow everything down. Debugging issues can take time, and streaming isn’t truly real-time. it still works in small batches. Also, it can be tricky to match the right Spark version with other tools in your setup. Review collected by and hosted on G2.com. What problems is Spark solving and how is that benefiting you? Cleaning and preparing large datasets Automating daily data processing tasks Handling both batch and near real-time data flows Running reports and analytics jobs Review collected by and hosted on G2.com.

Application Developer Computer Software Enterprise (\> 1000 emp.) 9/30/2023 "Extraordinary Big data processing and optimization." 4.5/5 What do you like best about Spark? I love the speed of data processing. Also the Immense Ecosystem of integration with APIs and the huge amount of optimization in memory we can achieve through it. It is very easy to use and implement with versatile data processing approaches we can achieve through it and also the customer support with community help is great! Review collected by and hosted on G2.com. What do you dislike about Spark? It needs a steep learning curve as non-tech persons or beginners may find it very complex. When the data complexity is huge, it is hard to debug and find bugs in the processed big data. It is not suitable for small data processing. Review collected by and hosted on G2.com. What problems is Spark solving and how is that benefiting you? It's solving a big problem by decreasing memory storage using optimization techniques, which thus solves the problem of buying big storage resources. Also, it has built-in fail-safe and security features ensuring data safety and integrity Review collected by and hosted on G2.com.

Senior Engineer | Data & Automation Enterprise (\> 1000 emp.) 5/25/2023 "Large scale data analytics on big data using Spark and Knime" 5/5 What do you like best about Spark? Integration with powerful scripting languages (Python, Scala and Java). Consume available Apache datastore files for developing ML models and quickly deploy to production. Integration with Knime provided no-code development of ETL pipelines, and merging with Apache datastores allowed us to quickly educate the traditional talent (SQL and Excel-based) to build robust data insights. Knime platform integration with Spark did not require any additional computing power as it performed all the processing on the Spark infrastructure. Review collected by and hosted on G2.com. What do you dislike about Spark? Out of the box, Spark has fewer algorithms for ML models, but we can extend with other programming languages which involves additional effort while implementing with Knime. Review collected by and hosted on G2.com. What problems is Spark solving and how is that benefiting you? Initially, Spark provided a quick and best way to consume the already available Apache datastores and build data science capabilities. When Knime came into the picture as a strategic tool, the rapid integration with Spark proved to extend the capabilities of Knime and an alternate way to consume Spark MLOps.

We can easily debug a spark issue by checking lineage on spark UI Review collected by and hosted on G2.com. What do you dislike about Spark? 1. Sometimes, out-of-memory errors on spark become very frequent, and a SIGKILL command is invoked without any proper stack trace by spark. This way it becomes very difficult to debug a spark job Review collected by and hosted on G2.com. What problems is Spark solving and how is that benefiting you?
