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.

What you get
  1. 1Explore tables across your Trino catalogs without exporting data or building another pipeline
  2. 2Author dbt models and tests against fully qualified catalog.schema.table relations
  3. 3Protect shared cluster capacity with load budgets measured in cluster-seconds and server-enforced query caps
In your repositoryDex

Agent-native analytics engineering for your dbt project.

How it works

Explore, transform, maintain: the Dex loop on Trino.

  1. 1

    Point 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
  2. 2

    Explore your catalogs

    /dex:explore inventories and profiles the tables in your allowed catalogs and schemas, infers relationships, and proposes what to model.

  3. 3

    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
  4. 4

    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.

  5. 5

    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.

Other warehouses

Dex brings the same loop and the same guardrails to each of these.
