# Data Warehouses

Connect your data warehouses to Euno to map your entire warehouse structure, track usage patterns, and optimize costs.

## Supported Warehouses

* [**Snowflake**](/sources/data-warehouses/snowflake-integration.md) - Cloud data warehouse
* [**BigQuery**](/sources/data-warehouses/bigquery-integration.md) - Google's serverless data warehouse
* [**Databricks**](/sources/data-warehouses/databricks-integration.md) - Unified analytics platform
* [**MySQL**](/sources/data-warehouses/mysql-integration.md) - Relational database

## What You'll Get

When you connect a data warehouse, Euno discovers:

* **Tables and Views** - All tables, views, and their schemas
* **Columns** - Column-level metadata and lineage
* **Usage Data** - Query patterns, costs, and performance metrics
* **Storage Information** - Table sizes and growth trends
* **Relationships** - Dependencies between tables and views

## Common Use Cases

* **Cost Optimization** - Identify expensive, unused tables
* **Lineage Mapping** - Understand data flow across your warehouse
* **Governance** - Track which tables are managed by dbt vs. ad-hoc
* **Performance** - Find slow queries and optimization opportunities

## Getting Started

1. Choose your warehouse from the list above
2. Follow the setup guide for your platform
3. Grant Euno read access to metadata and query logs
4. Run your first sync

**Setup Time:** 15-20 minutes per warehouse
