MLeap is a portable execution engine for deploying machine learning pipelines from Spark and Scikit-learn without their runtime dependencies.
MLeap is an execution engine and serialization library that allows machine learning pipelines trained in Apache Spark or Scikit-learn to be exported to a portable format and run in production without their original dependencies. It solves the problem of deploying ML models by providing a lightweight runtime that eliminates the need for Spark Context or Python scientific stacks in serving environments.
Data scientists and ML engineers who train models in Spark or Scikit-learn and need to deploy them into production systems where framework dependencies are impractical.
Developers choose MLeap because it provides a unified, dependency-free runtime for models from multiple frameworks, enabling faster and more portable ML deployments with maintained parity to training environments.
MLeap: Deploy ML Pipelines to Production
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Exports models from Spark, PySpark, and Scikit-learn to a common Bundle.ML format (JSON or Protobuf), enabling a unified runtime without original dependencies like Spark Context or NumPy.
Executes serialized pipelines without requiring heavy training frameworks in production, reducing resource footprint and simplifying deployment in microservices or JVM environments.
Includes extensive test coverage to ensure MLeap pipelines produce identical results to their Spark or Scikit-learn counterparts, minimizing deployment risks.
Provides APIs to implement custom data types and transformers, allowing integration with specialized workflows beyond built-in support.
The strict dependency compatibility matrix ties MLeap versions to specific Spark, Scala, Java, and Python releases, making upgrades cumbersome and error-prone.
Does not support all Spark or Scikit-learn transformers out-of-the-box, requiring custom implementations for missing features, which adds development overhead.
Primarily built on the JVM with Scala, which can be a hurdle for Python-centric teams despite PySpark integration, as it introduces additional tooling and learning curves.
