NifflerDB

NifflerDB is a simple, embeddable and persistent key-value store implemented as a B+ tree.

Hello World

#include "niffler/db.h"

int main(int argc, char* argv[])
{
    // true will truncate the file if it exists
    auto niffler = std::make_unique<niffler::db>("hello_world.ndb", true);
    niffler->insert("Hello World!", "Hello World!");
    
    return 0;
}

Public API(thread safe)

std::unique_ptr<find_result> find(const key& key) const;
bool exists(const key& key) const;
bool insert(const key& key, const void *data, u32 data_size);
bool remove(const key& key);

TODO

• Better error handling
• Support for multiple "buckets"
• Unused pages clean-up
• Memory-mapped I/O?
• Transactions?

OS Support

Only runs on Windows(at least right now) and has only been tested with the Visual C++ Compiler.
