Project Title

rocksdb — A High-Performance, Embeddable Persistent Key-Value Store for Flash and RAM Storage

Overview

RocksDB is an embeddable, persistent key-value store library developed and maintained by Facebook's Database Engineering Team. It is designed for fast storage, especially on flash drives, and offers flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF), and Space-Amplification-Factor (SAF). With multi-threaded compactions, RocksDB is well-suited for handling multiple terabytes of data in a single database.

Key Features

Log-Structured-Merge-Database (LSM) design for efficient storage
Multi-threaded compactions for improved performance
Flexible tradeoffs between WAF, RAF, and SAF
Support for storing large amounts of data (multiple terabytes) in a single database

Use Cases

Use case 1: Storing large-scale data on flash drives
Use case 2: Building fast key-value servers for high-performance applications
Use case 3: Managing databases with high write and read amplification factors

Advantages

Advantage 1: Optimized for flash and RAM storage, providing fast data access
Advantage 2: Built on the earlier work of LevelDB, leveraging proven technology
Advantage 3: Dual-licensed under both GPLv2 and Apache 2.0, offering flexibility in licensing options

Limitations / Considerations

Limitation 1: May require significant resources for large-scale deployments
Limitation 2: Internal APIs may change without warning, affecting custom implementations

LevelDB: The predecessor to RocksDB, offering a simpler key-value store solution.
LMDB: A high-performance, memory-mapped database with a focus on transactional integrity.
SQLite: A widely-used, serverless, self-contained database engine that is not designed for high write amplification scenarios like RocksDB.
