Amigo was designed to accelerate queries directed at an existing data warehouse while leaving the data warehouse as the database of record. In contrast Maverick was designed as a stand-alone data store. ParAccel discontinued Amigo in favor of the stand-alone  offering which evolved into the ParAccel Analytic Database (PADB).

ParAccel implements compiled queries, and a proprietary interconnect protocol for inter-node communications. ParAccel offered on-demand integration (ODI) modules for analytics and data outside of the ParAccel Analytic Platform
