BlazingDB is an open source, scalable storage engine for PostgreSQL. It is developed by Red Hat Software in collaboration with the community. BlazingDB provides a number of features including parallel query execution, caching, compression and replication. I like the fact that it is built on top of PostgreSQL which is one of the most popular databases out there. The documentation could be more detailed and comprehensive. I am solving problems with large amounts of data and blazingDB helps me to solve them quickly and effectively.
