Introduction to LakeSoul
LakeSoul is an innovative cloud-native Lakehouse framework designed to seamlessly handle the complexities of modern data management challenges. This versatile system stands out by offering scalable metadata management, robust ACID transactions, efficient data operations, schema evolution capabilities, and unified processing for both streaming and batch data.
Core Features
Flexible Data Processing
LakeSoul supports various computing engines like Spark, Flink, Presto, and PyTorch, enabling users to efficiently read and write lake warehouse table data. It accommodates different processing modes, including batch, stream, massively parallel processing (MPP), and AI, making it highly adaptable for diverse computing needs. Additionally, LakeSoul is compatible with storage systems such as HDFS and S3.
Incremental Upserts and High Write Throughput
A key feature of LakeSoul is its ability to handle incremental upserts for rows and columns, which permits concurrent data updates. Utilizing an LSM-Tree-like structure, LakeSoul supports updates on hash-partitioned tables using primary keys, achieving high write throughput with optimized read performance.
Diverse Integration and Interfaces
Built with Rust for its native metadata and IO layers, LakeSoul provides interfaces in C, Java, and Python. This flexibility allows it to integrate seamlessly with various computing frameworks used in big data and AI environments.
Reliable and Concurrent Operations
LakeSoul is designed to support concurrent batch or streaming read and write operations, all within a reliable framework providing Change Data Capture (CDC) semantics, auto schema evolution, and exactly-once guarantees. This makes the construction of real-time data warehouses straightforward and efficient.
Security and Permission Management
The framework includes multi-workspace support and role-based access control (RBAC). By leveraging PostgreSQL's RBAC policies, it ensures metadata permission isolation. Combined with Hadoop's user and group policies, it achieves robust physical data isolation.
Automation and Cost Efficiency
To further enhance its utility, LakeSoul features automatically disaggregated compaction, table lifecycle management, and redundant data cleaning. These automatic processes not only reduce operational overhead but also increase system usability.
Community and Contributions
