HeavyDB (formerly MapD/OmniSciDB)
This is a SQL-based, columnar database engine designed for lightning-fast analysis of extremely large datasets. It takes in multi-billion row tables and outputs query results in milliseconds, even without complex setup like indexing. Data analysts, business intelligence specialists, and data scientists working with massive amounts of raw data will find this tool invaluable.
3,060 stars.
Use this if you need to perform interactive, real-time queries on colossal datasets and get answers back almost instantly.
Not ideal if your data volumes are small to moderate, or if you primarily work with unstructured data that isn't suited for a relational, columnar format.
