A library for writing Apache Spark applications in Haskell, enabling resilient analytics that scale to thousands of nodes.
Sparkle is a library that enables developers to write Apache Spark applications in Haskell, compiling them into self-contained JAR files for execution on Spark clusters. It solves the problem of applying Haskell's strong typing and functional paradigms to large-scale, distributed data processing tasks typically handled by Spark.
Haskell developers and data engineers who need to build scalable, type-safe analytics applications on Apache Spark, particularly those already invested in the Haskell ecosystem.
Developers choose Sparkle to leverage Haskell's expressiveness and reliability in big data contexts, avoiding the limitations of Java/Scala while still utilizing Spark's proven distributed computing framework.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Enables writing Spark jobs with Haskell's strong type system, reducing runtime errors and improving code reliability, as emphasized in the project's philosophy for resilient analytics.
Compiles Haskell code into deployable JAR files that embed native object code and dependencies, simplifying distribution across Spark clusters, as described in the 'How it works' section.
Supports embedding Java code fragments directly in Haskell using the `inline-java` library, facilitating interoperability with Java-based Spark APIs and easing transitions.
Leverages Spark's framework to scale applications to thousands of nodes, making it suitable for large-scale data processing on local or cluster deployments.
Requires Nix, Bazel, and specific configurations like setting CLASSPATH and JNI paths, making initial setup and maintenance challenging, as detailed in the build instructions for Linux and other platforms.
Prone to problems like ClassNotFoundException and UnsatisfiedLinkError, especially in multi-threaded environments, necessitating error handling as noted in the troubleshooting section.
Has a smaller community and fewer resources compared to Scala or Python Spark APIs, which can hinder development and troubleshooting, evident from niche adoption and specific workarounds needed.
