DescriptionNatively in-memory DBMS with options for persistency, high-availability and clusteringGrakn is a distributed, hyper-relational database for managing complex data that serves as a knowledge base for cognitive/AI systems.In-memory data structure store, used as database, cache and message broker infoRedis focuses on performance so most of its design decisions prioritize high performance and very low latencies.
Primary database modelRelational DBMS
Time Series DBMS
Graph DBMS
Relational DBMS infoOften described as a 'hyper-relational' database, since it implements the 'Entity-Relationship Paradigm' to manage complex data structures and ontologies.
Key-value store infoMultiple data types and a rich set of operations, as well as configurable data expiration, eviction and persistence
