Exasol Database

Exasol is an in-memory columnar analytics database designed for complex queries on massive datasets. Unlike traditional row-oriented databases (PostgreSQL), Exasol stores data in columns, compressing each column independently and executing queries across hundreds of CPU cores in parallel. The result: billion-row queries return in seconds instead of minutes or hours. Exasol is deployed on-premise or in cloud (AWS, GCP, Azure) and integrates with Tableau, Looker, and custom BI applications for real-time dashboards.
