Overview Quickstart dbt Compatibility The Style Guide profiles.yml sources.yml Configuration Supported Databases

MYSQL

The world's most popular open-source database. Widely used for operational/transactional workloads and web applications.

DVT SUPPORT

✓ FEDERATION SOURCE

read in federation models

✓ FEDERATION TARGET

materialize federation results

✓ DEFAULT TARGET

run full dbt projects against it

✓ SEED TARGET

dvt seed --target loads here

DVT supports MySQLbecause both dbt and Sling do: dbt drives standard materializations when it's your default target, Sling moves data in and out during federation. Connectivity for both layers is checked with dvt debug --all.
