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.
Built with modern database design principles for mission-critical applications
Log-Structured Merge tree architecture optimized for high write throughput with automatic background compaction and intelligent level management.
Multi-Version Concurrency Control ensures non-blocking reads and writes with snapshot isolation and full ACID transaction support.
Write-Ahead Logging captures full transaction state for recovery and rehydration. Configurable sync options balance performance with durability requirements.
Scalable design with background flusher and compactor. Sustains 100K+ transactions per second with hundreds of thousands of reads per second.
Automatic crash recovery restores all in-flight and committed transactions. Incomplete transactions are preserved and accessible after crashes.
Range, prefix, and full iteration support with bidirectional traversal. Optional Bloom filters per SSTable for fast key lookups.
Industry-standard components engineered for reliability and performance
Multi-level Log-Structured Merge tree with size-tiered and leveled compaction strategies for optimal space utilization and query performance.
Lock-free skip list implementation with MVCC version chains for fast in-memory access and concurrent modification support.
BTree-based SSTables with key-value separation optimization, leveraging efficient block storage with direct I/O operations.
Durable and concurrent block storage using direct, offset-based file I/O with pread/pwrite for optimal performance and control.
Full ACID compliance with atomic write paths, snapshot isolation, and comprehensive crash recovery capabilities.
Multi-threaded background compaction and flushing with configurable concurrency limits and intelligent scheduling.
Perfect for applications requiring sustained high write throughput with strong consistency guarantees and concurrent access patterns.
Lightweight embedded storage engine for applications requiring local data persistence.
Fast range queries and prefix iteration support make it ideal for real-time analytics and time-series data processing.
Full ACID compliance with snapshot isolation ensures data integrity for financial and mission-critical transaction processing.
High-performance key-value operations with configurable durability options for caching and session management systems.
Lightweight footprint with robust crash recovery makes it suitable for IoT devices and edge computing scenarios.
