Splinter: A High-Performance Vector Anti-Database and Shared Memory Substrate

Splinter is an innovative, minimalist, lock-free key-value (KV) manifold tailored for high-frequency data ingestion and retrieval across separate application runtimes. By eliminating the complexities of the kernel's networking stack, Splinter achieves unparalleled efficiency in local inter-process communications (IPC), providing L3 speeds without the latency typically associated with traditional socket-based architectures.

Key Features and Advantages

• Passive Substrate: Instead of functioning as a daemon, Splinter acts as a memory-mapped region that offers mutual access for every process on the system, minimizing overhead.
• Zero-Copy Intent (DRYD): Information is published rather than sent, allowing readers to access raw memory directly while maintaining safety with minimal checkpoints, thus enhancing performance by reducing serialization costs.
• Static Geometry: Utilizes a fixed-geometry arena to avoid issues with dynamic heap fragmentation and garbage collection, ensuring stability and predictable performance.
• Lock-Free Operations: Standard portable atomic sequence locks replace traditional mutex locks, providing faster access to data.
• NUMA Compatibility: Supports non-uniform memory access (NUMA) on modern hardware, potentially reaching write speeds of near 500 million operations per second.
• Inference Engine: Comes equipped with a sidecar embedding engine that runs asynchronously, integrating Nomic Text embedding capabilities efficiently.
• Extensibility: Offers Lua scripting for easy data transformation and allows loadable shards for enhanced modularity without bloating the core functionality.
• Optimized Performance: With validated throughput exceeding 3.2 million operations per second and exceptionally low latency, Splinter excels in demanding environments such as AI inference and high-resolution physics data collection.

Architectural Philosophy

Splinter is predicated on simplifying system architectures for performance. It addresses common pitfalls in modern software where reliance on overly complex abstractions leads to inefficiencies. By focusing on metrics such as throughput and latency, Splinter provides a tool that minimizes unnecessary interactions with the kernel and maximizes the use of available hardware resources.

Use Cases

• High-Resolution Physics & Statistics Research: Captures and processes high-frequency data at L3 speeds, making it suitable for experiments requiring fine-grained data integrity and speed.
• Large Language Model Memory Optimization: Serves as an effective memory management solution for large language models, allowing efficient access and storage of embeddings while maintaining swift inference times.
• Configuration Management: Can manage application configurations on Linux systems, providing a robust foundation for RESTful endpoint exposure.
• Lightweight KV Store: Can function purely as a socket-less KV store, offering developers a way to efficiently manage and deliver data without the overhead of traditional database systems.

Performance and Scalability

Splinter's design ensures it remains usable across a wide variety of platforms, including modern GNU/Linux distributions, with potential adaptations for Windows and MacOS. Its core library is intentionally concise, at just 875 lines of code, maintaining a lightweight footprint while ensuring high performance.

Conclusion

Splinter stands out as a unique solution for developers and researchers seeking high-speed, reliable, and lock-free data storage options. By focusing on efficient memory use and process interaction, it positions itself as an essential tool for applications that demand the highest performance in data handling.
