Under the Hood: Building and open-sourcing RocksDB

This post introduces RocksDB, an embeddable, persistent key-value store developed and open-sourced by Meta. It addresses the challenge of storing and accessing hundreds of petabytes of data efficiently for real-time, user-facing applications. RocksDB is built on LevelDB and is designed to scale on multi-core servers, efficiently utilize fast storage (like flash), offer a flexible architecture for innovation, and support various workloads (IO-bound, in-memory, write-once). It aims to reduce network latency by enabling applications to manage their own datasets locally and improve performance by minimizing lock contention and optimizing storage operations.
