MARIADB

Community-developed fork of MySQL. Drop-in replacement with enhanced performance and additional storage engines.

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 MariaDBbecause 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.

DBT ADAPTER FEATURES

When MariaDB is your default target, every standard dbt model runs through the official dbt adapter — all of its documented capabilities apply unchanged:

NOTABLE CONFIGS

▸MySQL-wire compatible (uses the mysql adapter)

FEDERATION INCREMENTAL STRATEGIES

Strategies available when this engine is the target of a f_incremental model:

✓ Append✓ Delete+Insert✓ Merge

KNOWN LIMITATIONS

⚠Uses MySQL protocol — same driver as MySQL
