Adapters

There are two major adapter types: base and sql.

`base`

BaseAdapter defines the base functionality an adapter is required to implement in order to function with dbt-core. There are several methods which have default implementations as well as methods that require the concrete adapter to implement them.

`sql`

SQLAdapter inherits from BaseAdapter, updates default implementations to work with SQL-based platforms, and defines additional required methods to support those defaults.

Components

An adapter is composed of several components.

connections
dialect
relation caching
integration with dbt-core

The first two are platform-specific and require significant implementation in a concrete adapter. The last two are largely implemented in dbt-adapters with minor adjustments in a concrete adapter.

Connections

This component is responsible for creating and managing connections to storage and compute.

Dialect

This component is responsible for translating a request from dbt-core into a specific set of actions on the platform.

Relation caching

This component is responsible for managing a local cache of relations, relation metadata, and dependencies between relations.

dbt/adapters/cache.py

Integration with `dbt-core`

This component is responsible for managing the interface between dbt-core and a concrete adapter.
