Overview of LakeSail
LakeSail: Rethink Spark for Modern Data & AI
What is LakeSail?
LakeSail is a multimodal distributed framework designed for batch processing, streaming, and AI workloads. Built in Rust, it serves as a drop-in replacement for Apache Spark, offering improved performance, reduced costs, and a familiar Apache Spark interface. This unified, cloud-native engine is suitable for various applications, from small-scale projects on laptops to large-scale deployments in the cloud.
Key Features and Benefits
- Lower Costs: Save up to 94% on cloud bills while achieving more with the same budget.
- No Code Changes: Utilize existing Spark SQL and DataFrame APIs without complex migration efforts.
- Faster Execution: Experience up to 4x faster execution speeds, enabling quicker insights from data.
- No JVMs: Benefit from a Rust-native engine that eliminates memory issues and garbage collection pauses.
How does LakeSail work?
LakeSail provides a single entry point for batch, streaming, and AI tasks. It integrates compute closer to your data lakehouse and AI models and offers parity with Apache Spark, allowing you to use existing Spark code with minimal changes. The architecture is cloud-native by design, supporting autoscaling, observability, and decoupled storage.
The core of LakeSail is built with Rust, which enables efficient memory management and concurrency, leading to improved performance and safety. It also supports lightning-fast UDFs, allowing Python code to run seamlessly within query execution without the Py4J bridge.
