What We Need Help With

We need help creating a new adapter to connect Intugle to Amazon Redshift. This will allow users to profile, analyze, and generate data products from their Redshift data warehouses.

Background & Context

Intugle is designed to be extensible, and we want to expand our support for common data warehouses. Redshift is a popular choice, and adding an adapter for it will significantly increase the tool's utility. This task involves creating a new adapter that implements the same interface as our existing adapters, like the one for Postgres.

Current State

Currently, Intugle does not have a native connector for Amazon Redshift. Users who want to work with Redshift data have to manually export it to a format that Intugle supports (like CSV or Pandas DataFrame).

Desired Outcome

A new, fully functional Redshift adapter that is integrated into the Intugle framework. This means a user should be able to configure their Redshift connection in profiles.yml and use Intugle to:

• Connect to a Redshift instance.
• Profile tables and columns.
• Execute queries.
• Create new tables/views from queries.
• Perform semantic searches and build data products.

Scope of Work

• Create the basic scaffolding for the Redshift adapter (src/intugle/adapters/types/redshift/).
• Define the Pydantic models for Redshift connection and data configuration (models.py).
• Implement the RedshiftAdapter class, inheriting from intugle.adapters.adapter.Adapter (redshift.py).
• Implement all the abstract methods of the Adapter class for Redshift.
• Register the new adapter in the adapter factory so it's discoverable by the system.
• Add optional dependencies for the Redshift driver (e.g., redshift_connector) to pyproject.toml.
• Add unit tests for the new adapter.

Technical Details

Checkout the documentation on how to implement a adapter : Implementing a Connector
The new adapter should follow the pattern of the existing PostgresAdapter. It will need to handle the specifics of connecting to Redshift and translating Intugle's operations into Redshift-compatible SQL.

Relevant Files/Modules

• src/intugle/adapters/types/postgres/ (as a reference)
• src/intugle/adapters/types/redshift/ (to be created)
• src/intugle/adapters/factory.py (to register the new adapter)
• pyproject.toml (to add optional dependencies)
• tests/adapters/ (to add new tests)

Key Concepts/Technologies

• Amazon Redshift & its SQL dialect
• Python
• Pydantic

Related Documentation

• Implementing a Connector

Suggested Approach

Use the PostgresAdapter as a template. Much of the logic will be similar, as Redshift is based on PostgreSQL. The main differences will likely be in the connection handling and the specific SQL syntax for certain operations.

Skills Needed

• Python development
• Data engineering
• SQL and database knowledge
• Testing (pytest)
• Documentation writing

Difficulty Level

• Intermediate - Familiarity with data engineering concepts

Time Estimate

• Medium (a few days)

Getting Started

1. Fork the repository.
2. Set up your development environment (see CONTRIBUTING.md).
3. Follow the Implementing a Connector guide.
4. Use the PostgresAdapter implementation as a reference for your RedshiftAdapter.

Testing Requirements

• Unit tests for the new RedshiftAdapter class.
• Integration tests (if possible, with a mock or local Redshift instance).
• Documentation examples.

Additional Context

Note on Dependencies: When choosing a database driver or any other external library, please ensure its license is permissive (e.g., MIT, Apache 2.0) to be compatible with this project's Apache 2.0 license.
