In a nutshell, EinsteinDB is a persistent indexing scheme based off of LSH-KVX that exploits the distinct merits of hash index and B+-Tree index to support range scan and avoids long NVM writes for maintaining consistency; thus improving on LSH’s performance guarantees for skewed data and adopts ordered-write consistency to ensure crash consistency, while retaining the same storage and query overhead.
