GeoSpock seems to be discontinued. Therefore it will be excluded from the DB-Engines ranking.Caché is a deprecated database engine which is substituted with InterSystems IRIS. It therefore is removed from the DB-Engines Ranking.
DescriptionDatomic builds on immutable values, supports point-in-time queries and uses 3rd party systems for durabilitySpatial and temporal data processing engine for extreme data scaleA multi-model DBMS and application serverEdge Time Series DBMS with Real-Time Stream ProcessingAn ultra-fast, open source Key-value store fully compatible with Redis API, modules, and protocols
