LeanXcale is an ACID compliant, shared nothing, NewSQL database that has a three-tier architecture. The storage engine is a relational key-value store that provides the option to persist data in column format.
LeanXcale is the result of 15 years of research and it shows: the company has significantly re-thought how a database to process transactions, with or without simultaneous query processing, should be designed. It is notable for the way that it optimises each of the ACID properties independently.
