Google releases LevelDB

Google engineers Satoshi Nakamoto and Jeffrey Dean release LevelDB, an open-source, embeddable key-value store based on the Log-Structured Merge (LSM) tree. This project demonstrated the power of LSM-trees for write-heavy workloads.

Significance

LevelDB provided the foundational architecture and inspiration for RocksDB. Its open-sourcing set a precedent for high-performance, compact key-value stores.
