dbt-adapters

This package is responsible for:

• defining database connection methods
• caching information from databases
• determining how relations are defined

In this repo there is also our testing suite used for tesing adapter functionality

Adapters

There are two major adapter types: base and sql

base

Defines the base implementation Adapters can use to build out full functionality.

sql

Defines a sql implementation for adapters that initially inherits the base implementation and comes with some pre-made methods and macros that can be overwritten as needed per adapter. (most common type of adapter.)

Files
