What is RocksDB?
An embeddable persistent key-value store written in C++ optimized for fast, low-latency storage such as flash drives and high-speed disk drives.

The Vioscale score: one lens on the evidence
Not user reviews and not a paid placement: a confidence-weighted blend of the independent signals below (adoption, activity, security posture, and more), which you can sort and re-weight yourself. Vendors can correct their listing but can never move their rank, and stars are weighted low as a vanity metric. It is one way to read the evidence for RocksDB, not the verdict.
