Trino
AvailableDatabases
Self-hosted Trino, Starburst Enterprise, and Trino on Amazon EMR. Dex explores your catalogs, authors dbt models, and detects drift with cluster-load guards.
Why connect Trino?
Dex works with self-hosted Trino, Starburst Enterprise, and Trino on Amazon EMR to explore your catalogs, author dbt models, and detect drift across the data sources Trino already connects.
- Explore tables across your Trino catalogs without exporting data or building another pipeline
- Author dbt models and tests against fully qualified catalog.schema.table relations
- Protect shared cluster capacity with load budgets measured in cluster-seconds and server-enforced query caps
Works with Dex
Trino connects to the Exmergo products your team already uses.
How it works
Connecting Trino to
Exmergo DexCost guard: cluster-secondsPoint Dex at Trino
Install Dex in Claude Code by running /plugin marketplace add exmergo/exmergo-agent-plugins and /plugin install dex@exmergo. Set connector: trino in .dex/config.yml. Dex discovers your connection through TRINO_URL, the TRINO_* environment, configured connection coordinates, or an existing dbt profile; credentials stay outside the model context.
$ /plugin marketplace add exmergo/exmergo-agent-plugins
$ /plugin install dex@exmergo
Explore your catalogs
/dex:explore inventories and profiles the tables in your allowed catalogs and schemas, infers relationships, and proposes what to model.
$ /dex:explore
Author governed dbt models
/dex:transform authors dbt models and tests through dbt-trino, with builds targeting your configured development catalog and schema.
$ /dex:transform
Stay inside a cluster-load guard
Dex estimates scan load before execution and asks for confirmation before running metered work. Budgets are measured in cluster-seconds, with server-enforced runtime and physical scan caps to protect shared capacity.
Catch drift automatically
/dex:maintain detects schema, volume, and grain drift in your Trino sources and proposes reviewable changes to keep your project in sync.
