NameAmazon DynamoDB  Xexclude from comparisonCouchbase infoOriginally called Membase  Xexclude from comparisonLevelDB  Xexclude from comparisonRedis  Xexclude from comparisonRRDtool  Xexclude from comparison
DescriptionHosted, scalable database service by Amazon with the data stored in Amazons cloudA distributed document store with integrated cache, a powerful search engine, in-built operational and analytical capabilities, and an embedded mobile databaseEmbeddable fast key-value storage library that provides an ordered mapping from string keys to string valuesPopular in-memory data platform used as a cache, message broker, and database that can be deployed on-premises, across clouds, and hybrid environments infoRedis focuses on performance so most of its design decisions prioritize high performance and very low latencies.Industry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database. infoThe data is stored in a circular buffer, thus the system storage footprint remains constant over time.
