DescriptionServerless Time Series DBMSFully managed big data interactive analytics platformA DBMS designed for efficient storage of vector data and vector similarity searchesWidely used in-process key-value storeA key-value store forked from RocksDB with advanced compression algorithms. It can be used standalone or as a storage engine for MySQL and MongoDB
Primary database modelTime Series DBMSRelational DBMS infocolumn orientedVector DBMSKey-value store infosupports sorted and unsorted key sets
Native XML DBMS infoin the Oracle Berkeley DB XML version
