Workers

Workers are the unit of compute in Altertable. They execute DuckDB SQL, read and write lakehouse files, connect to data sources, cache hot data locally, and stream query results back to your application.

Workers are stateless. You can scale compute without moving storage, and idle compute can disappear while the catalog remains durable in object storage.

Managed Workers

Managed Workers run on Altertable infrastructure and are the default for new environments. Today, managed Workers are available on Hetzner in Europe (Germany).

We can provision managed Workers on AWS or Google Cloud on demand for teams with cloud, residency, or procurement requirements.

Self-hosted Workers

Self-hosted Workers are designed for teams that need compute inside their own cloud. A Worker can run from a container image, so queries run close to your buckets and databases instead of moving large datasets across cloud boundaries. That keeps data egress predictable and helps avoid cross-cloud transfer fees.
