High-Performance Embedded Key-Value Storage Engine
LSM-tree architecture with MVCC, lock-free concurrency, and ACID transactions. Built for modern applications that demand both performance and reliability.
High-Class Features
Built with modern database design principles for mission-critical applications
High-Performance LSM
Log-Structured Merge tree architecture optimized for high write throughput with automatic background compaction and intelligent level management.
Lock-Free MVCC
Multi-Version Concurrency Control ensures non-blocking reads and writes with snapshot isolation and full ACID transaction support.
WAL & Durability
Write-Ahead Logging captures full transaction state for recovery and rehydration. Configurable sync options balance performance with durability requirements.
Concurrent Operations
Scalable design with background flusher and compactor. Sustains 100K+ transactions per second with hundreds of thousands of reads per second.
Crash Recovery
Automatic crash recovery restores all in-flight and committed transactions. Incomplete transactions are preserved and accessible after crashes.
Advanced Indexing
Range, prefix, and full iteration support with bidirectional traversal. Optional Bloom filters per SSTable for fast key lookups.
Proven Architecture
Industry-standard components engineered for reliability and performance
LSM Tree Storage
Multi-level Log-Structured Merge tree with size-tiered and leveled compaction strategies for optimal space utilization and query performance.
Version-Aware Skip Lists
Lock-free skip list implementation with MVCC version chains for fast in-memory access and concurrent modification support.
Immutable SSTables
BTree-based SSTables with key-value separation optimization, leveraging efficient block storage with direct I/O operations.
Atomic Block Manager
Durable and concurrent block storage using direct, offset-based file I/O with pread/pwrite for optimal performance and control.
Transaction Management
Full ACID compliance with atomic write paths, snapshot isolation, and comprehensive crash recovery capabilities.
Background Operations
Multi-threaded background compaction and flushing with configurable concurrency limits and intelligent scheduling.
Use Cases
High-Throughput Applications
Perfect for applications requiring sustained high write throughput with strong consistency guarantees and concurrent access patterns.
Embedded Database Systems
Lightweight embedded storage engine for applications requiring local data persistence.
Real-Time Analytics
Fast range queries and prefix iteration support make it ideal for real-time analytics and time-series data processing.
Transaction Processing
Full ACID compliance with snapshot isolation ensures data integrity for financial and mission-critical transaction processing.
Caching & Session Storage
High-performance key-value operations with configurable durability options for caching and session management systems.
IoT & Edge Computing
Lightweight footprint with robust crash recovery makes it suitable for IoT devices and edge computing scenarios.
