JSqlDB seems to be discontinued. Therefore it is excluded from the DB-Engines ranking.Titan has been decommisioned after the takeover by Datastax. It will be removed from the DB-Engines ranking. A fork has been open-sourced as JanusGraph.
DescriptionDatomic builds on immutable values, supports point-in-time queries and uses 3rd party systems for durabilityDBMS for storing time series, events and metricsJavaScript Query Language Database, stores JavaScript objects and primitivesIn-memory key-value store, originally intended for cachingTitan is a Graph DBMS optimized for distributed clusters.
