## What it is
A lightweight key-value storage engine implemented in C++ using a skiplist as the core data structure, supporting insert, delete, search, display, persistence to disk, and file loading. It is primarily an educational project demonstrating how skiplist-based engines like Redis, LevelDB, and RocksDB work, with benchmark scripts included.

## Use cases
- learn how skiplist-based kv storage engines work
- embed a simple key-value store in a C++ program
- benchmark in-memory key-value read/write performance
- study persistence and file loading in a storage engine
- practice C++ data structure implementation

## When to choose
- you want a tiny, header-only key-value store for learning or lightweight use
- you need a simple C++ skiplist implementation to study or extend
- you want a starting point for building a storage engine

## When to avoid
- you need production-grade durability, concurrency, or crash recovery
- you need non-integer keys without writing custom comparators
- you need a distributed or network-accessible database

## Facets
- artifact type: library
- maturity: stable
- function: database, search-engine, benchmarking
- domain: databases, developer-tools, education
- platform: cpp, cross-platform
- tags: skiplist, key-value-store, storage-engine, kv-store, learning-project, in-memory-database, algorithms, linux
