hamsterdb Embedded Storage is a lightweight embedded "NoSQL" key-value store. It is in development for more than five years and concentrates on ease of use, high performance, stability and scalability.

The hamsterdb Embedded Storage API is simple and self-documenting. Extensive documentation, FAQ and a tutorial are provided. The interface is similar to other widely-used database engines.

Fast algorithms and data structures guarantee high performance for all scenarios. The implementation of these algorithms minimizes disk access and operating system calls (i.e. memory allocations). Data structures try to take advantage of modern CPU caches. Memory mapped file operations are preferred to the slower read/write I/O.

hamsterdb Embedded Storage has hundreds of unittests with a high test coverage. Each release is tested with thousands of acceptance tests in many different configurations, tested on up to six different hardware architectures and operating systems.

Written in plain ANSI-C, hamsterdb Embedded Storage runs or has been reported to run on many architectures: Intel-compatible (x86, x64), PowerPC, SPARC, ARM, RISC and others. Tested operating systems include Microsoft Windows, Microsoft Windows CE, Linux, SunOS and other Unices. The file format is endian-independent.
