Exasol

Exasol is an in-memory analytics database and data warehouse for many concurrent users and AI agents, deployable as SaaS, on premises or in hybrid setups.

Exasol answers SQL queries over billions of rows in seconds, for organizations whose dashboards, applications and AI agents hit the same data at the same time. Behind it is Exasol AG, a stock corporation founded in 2000 and headquartered in Nuremberg. The design centers on control: a customer chooses where data runs, how governance is enforced and how the infrastructure changes over time. Automatic self-indexing helps tune query performance. The Query cache answers a repeated identical query from stored results instead of running it again. Workload Management sorts sessions into consumer groups and enforces resource limits, ending queries that break them. Python 3 UDF scripts run inside the database, in parallel on every cluster node, so models work next to the data. Virtual schemas present tables from remote databases to Exasol SQL, and the Kafka Connector Extension imports Kafka topics into tables. The Exasol MCP server lets AI assistants such as Claude Desktop query the database directly. Exasol fits enterprise data teams modernizing a legacy warehouse, with published migration guides for Oracle and Teradata. It also suits organizations that must keep data on infrastructure they own, since the same database runs as Exasol SaaS, on premises or across hybrid environments. Exasol sets out a two-step path for buyers: developers start on Exasol Personal to build and test analytics and agent use cases, then production moves to Exasol Enterprise, arranged with Exasol's experts. The jobs it takes on are near real-time reporting on large tables, self-service analytics for business teams and machine learning inference on warehouse data. A data team loads Kafka topics and files from AWS S3, Azure Blob Storage or Google Cloud Storage, and connects data virtualization tools such as Denodo and Data Virtuality on top. Data loading and reporting can run side by side, each consumer group held to its own resource limits. Exasol suits companies that want fast SQL analytics and AI agents on infrastructure they control.
