DescriptionWide-column store based on ideas of BigTable and DynamoDB infoOptimized for write accessData warehouse and analytics appliance part of IBM PureSystemsOpen-source TimeSeries DBMS and monitoring systemPopular 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.
