## What is DataHub?
> **🔍 Finding the right DataHub?** This is the **open-source metadata platform** at [datahub.com](https://datahub.com) (GitHub: [datahub-project/datahub](https://github.com/datahub-project/datahub)). It was previously hosted at `datahubproject.io`, which now redirects to [datahub.com](https://datahub.com). This project is **not related to** [datahub.io](https://datahub.io), which is a separate public dataset hosting service. See the [FAQ](#-frequently-asked-questions) below.
**DataHub is the #1 open-source AI data catalog** that enables discovery, governance, and observability across your entire data ecosystem. Originally built at LinkedIn, DataHub now powers data discovery at thousands of organizations worldwide, managing millions of data assets.

**Prerequisites:**
- DataHub instance running (local or remote)
- Snowflake account with read permissions
- DataHub CLI installed (`pip install 'acryl-datahub[snowflake]'`)
```yaml
# snowflake_recipe.yml
source:
type: snowflake
config:
# Connection details
account_id: "xy12345.us-east-1"
warehouse: "COMPUTE_WH"
username: "${SNOWFLAKE_USER}"
password: "${SNOWFLAKE_PASSWORD}"
# Optional: Filter specific databases
database_pattern:
allow:
- "ANALYTICS_DB"
- "MARKETING_DB"
sink:
type: datahub-rest
config:
server: "http://localhost:8080"
```
```bash
# Run ingestion
datahub ingest -c snowflake_recipe.yml
# Expected output:
# ✓ Connecting to Snowflake...
# ✓ Discovered 150 tables in ANALYTICS_DB
# ✓ Discovered 75 tables in MARKETING_DB
# ✓ Ingesting metadata...
# ✓ Successfully ingested 225 datasets to DataHub
```
**What gets ingested:**
- Table and view schemas (columns, data types, descriptions)
- Table statistics (row counts, size, last modified)
- Lineage information (upstream/downstream tables)
- Usage statistics (query frequency, top users)
---
Example 2: Search for Datasets via Python SDK
**Use Case:** Programmatically search DataHub catalog and retrieve dataset metadata.
**Prerequisites:**
- DataHub instance accessible
- Python 3.8+ installed
- DataHub Python package installed (`pip install 'acryl-datahub[datahub-rest]'`)
```python
from datahub.ingestion.graph.client import DatahubClientConfig, DataHubGraph
# Initialize DataHub client
config = DatahubClientConfig(server="http://localhost:8080")
graph = DataHubGraph(config)
# Search for datasets containing "customer"
# Returns up to 10 most relevant results
results = graph.search(
entity="dataset",
query="customer",
count=10
)
# Process and display results
for result in results:
print(f"Found: {result.entity.urn}")
print(f" Name: {result.entity.name}")
print(f" Platform: {result.entity.platform}")
print(f" Description: {result.entity.properties.description}")
print("---")
# Example output:
# Found: urn:li:dataset:(urn:li:dataPlatform:snowflake,analytics.customer_profiles,PROD)
# Name: customer_profiles
# Platform: snowflake
# Description: Aggregated customer data from CRM and transactions
# ---
```
**Response format:** Each result contains:
- `urn`: Unique resource identifier for the dataset
- `name`: Human-readable dataset name
- `platform`: Source platform (snowflake, bigquery, etc.)
- `properties`: Additional metadata (description, tags, owners, etc.)
---
Example 3: Query Lineage via GraphQL
**Use Case:** Retrieve upstream and downstream dependencies for a specific dataset.
**Prerequisites:**
- DataHub GMS endpoint accessible
- Dataset URN available from search or ingestion
**GraphQL Query:**
```graphql
query GetLineage {
dataset(
urn: "urn:li:dataset:(urn:li:dataPlatform:snowflake,analytics.customer_profiles,PROD)"
) {
# Get upstream dependencies (source tables)
upstream: lineage(input: { direction: UPSTREAM }) {
entities {
urn
... on Dataset {
name
platform {
name
}
}
}
}
# Get downstream dependencies (consuming tables/dashboards)
downstream: lineage(input: { direction: DOWNSTREAM }) {
entities {
urn
type
... on Dataset {
name
platform {
name
}
}
... on Dashboard {
dashboardId
tool
}
}
}
}
}
```
**Execute via cURL:**
```bash
curl -X POST http://localhost:8080/api/graphql \
-H "Content-Type: application/json" \
-d '{"query": "query GetLineage { ... }"}'
```
**Response structure:**
- `upstream`: Array of datasets that feed into this dataset
- `downstream`: Array of datasets, dashboards, or ML models that consume this dataset
- Each entity includes URN, type, and basic metadata
---
Example 4: Add Documentation via Python API
**Use Case:** Programmatically add or update dataset documentation and custom properties.
**Prerequisites:**
- DataHub Python SDK installed
- Write permissions to DataHub instance
- Dataset already exists in DataHub (from ingestion)
```python
from datahub.metadata.schema_classes import DatasetPropertiesClass
from datahub.emitter.mce_builder import make_dataset_urn
from datahub.emitter.rest_emitter import DatahubRestEmitter
# Create emitter to send metadata to DataHub
emitter = DatahubRestEmitter("http://localhost:8080")
# Create dataset URN (unique identifier)
dataset_urn = make_dataset_urn(
platform="snowflake",
name="analytics.customer_profiles",
env="PROD"
)
# Define dataset properties
properties = DatasetPropertiesClass(
description="""
Customer profiles aggregated from CRM and transaction data.
**Update Schedule:** Updated nightly via Airflow DAG `customer_profile_etl`
**Data Retention:** 7 years for compliance
**Owner:** Data Platform Team
""",
customProperties={
"owner_team": "data-platform",
"update_frequency": "daily",
"data_sensitivity": "PII",
"upstream_dag": "customer_profile_etl",
"business_domain": "customer_analytics"
}
)
# Emit metadata to DataHub
emitter.emit_mcp(
entityUrn=dataset_urn,
aspectName="datasetProperties",
aspect=properties
)
print(f"✓ Successfully updated documentation for {dataset_urn}")
```
**What this does:**
1. Adds rich markdown documentation visible in DataHub UI
2. Sets custom properties for governance and discovery
3. Makes dataset searchable by custom property values
4. Enables filtered searches (e.g., "show me all PII datasets")
---
Example 5: Connect AI Coding Assistants via Model Context Protocol
**Use Case:** Enable AI agents (Cursor, Claude Desktop, Cline) to query DataHub metadata directly from your IDE or development environment.
**Prerequisites:**
- DataHub instance running and accessible
- MCP-compatible AI tool installed (Cursor, Claude Desktop, Cline, etc.)
- Node.js 18+ installed
**Quick Setup:**
```bash
# Initialize MCP server for DataHub
npx -y @acryldata/mcp-server-datahub init
# Follow the interactive prompts to configure:
# - DataHub GMS endpoint (e.g., http://localhost:8080)
# - Authentication token (if required)
# - MCP server settings
```
**Configure your AI tool:**
For **Claude Desktop**, add to `~/Library/Application Support/Claude/claude_desktop_config.json`:
```json
{
"mcpServers": {
"datahub": {
"command": "npx",
"args": ["-y", "@acryldata/mcp-server-datahub"]
}
}
}
```
For **Cursor**, configure in Settings → Features → MCP Servers
**What you can ask your AI:**
- _"What datasets contain customer PII in production?"_
- _"Show me the lineage for analytics.revenue_table"_
- _"Who owns the 'Revenue Dashboard' in Looker?"_
- _"Find all datasets in the marketing domain"_
- _"What's the schema for user_events table?"_
- _"List datasets tagged as 'critical' or 'sensitive'"_
**Example conversation:**
```
You: "What datasets are owned by the data-platform team?"
AI: Based on DataHub metadata, here are the datasets owned by data-platform:
- urn:li:dataset:(urn:li:dataPlatform:snowflake,analytics.customer_profiles,PROD)
Name: customer_profiles
Platform: Snowflake
Description: Aggregated customer data from CRM and transactions
- urn:li:dataset:(urn:li:dataPlatform:bigquery,marketing.campaign_performance,PROD)
Name: campaign_performance
Platform: BigQuery
Description: Marketing campaign metrics and ROI tracking
[... more results]
```
**Benefits:**
- ✅ Query metadata without leaving your IDE
- ✅ Natural language interface (no SQL/GraphQL needed)
- ✅ Real-time access to DataHub's metadata graph
- ✅ Understand data context while coding
