dbt-teradata 0.19.0.4

The Teradata adapter plugin for dbt (data build tool)

dbt-teradata

This plugin ports dbt functionality to Teradata Vantage.

Sample profile

Here is a working example of a dbt-teradata profile:

my-teradata-db-profile:
  target: dev
  outputs:
    dev:
      type: teradata
      host: localhost
      user: dbc
      password: dbc
      schema: dbt_test
      tmode: ANSI

At a minimum, you need to specify host, user, password, schema (database), tmode.

Optional configurations

Logmech

The logon mechanism for Teradata jobs that dbt executes can be configured with the logmech configuration in your Teradata profile. The logmech field can be set to: TD2, LDAP, KRB5, TDNEGO. For more information on authentication options, go to Teradata Vantage authentication documentation.

my-teradata-db-profile:
  target: dev
  outputs:
    dev:
      type: teradata
      host: <host>
      user: <user>
      password: <password>
      schema: dbt_test
      tmode: ANSI
      logmech: LDAP

Port

If your Teradata database runs on port different than the default (1025), you can specify a custom port in your dbt profile using port configuration.

my-teradata-db-profile:
  target: dev
  outputs:
    dev:
      type: teradata
      host: <host>
      user: <user>
      password: <password>
      schema: dbt_test
      tmode: ANSI
      port: <port>
