About:
Iowow is a high-performance C utility library featuring a persistent, mmap-based key/value storage engine. It provides ACID-compliant transactions, cursor iteration, and supports multiple database formats including B+ tree and fixed-length records. The library is designed for embedded use, offering zero-copy data access and efficient memory management.

Key Features:

Persistent mmap-based key/value storage engine
ACID-compliant transactions with cursor support
High performance with zero-copy data access
Multiple database formats (B+ tree, fixed-length, etc.)
Embedded C library with no external dependencies

Use Cases:

Embedded database for C/C++ applications
High-performance local data caching
Persistent storage for IoT and edge devices
Building custom database solutions

Alternatives:

LMDB – Iowow offers similar mmap performance with more flexible database formats and built-in utilities
RocksDB – Iowow is lighter weight and simpler for embedded use cases without LSM complexity
SQLite – Iowow provides raw key/value performance without SQL overhead for simpler access patterns
