Benchmark suite to evaluate HTAP database engines

evitaDB is a specialized database with an easy-to-use API for e-commerce systems. It is a low-latency NoSQL in-memory engine that handles all the complex tasks that e-commerce systems have to deal with on a daily basis. evitaDB is expected to act as a fast secondary lookup/search index used by front stores.

High Performance Learned Index on Persistent Memory

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 consiste…
