Introducing Badger: A fast key-value store written purely in Go - Dgraph Blog
Introducing Badger: A fast key-value store written purely in Go We have built an efficient and persistent log structured merge (LSM) tree based key-value store, purely in Go language. It is based upon WiscKey paper included in USENIX FAST 2016. This design is highly SSD-optimized and separates keys from values to minimize I/O amplification; leveraging both the sequential and the random performance
