Migrate Microsoft SQL Server to Databricks in 60 Seconds
Learn how to copy your Microsoft SQL Server data to Databricks with a single command using ingestr - no code required.
What you'll learn
Prerequisites
- Python 3.8 or higher installed
- SQL Server instance running
- SQL Server Authentication or Windows Authentication configured
- TCP/IP protocol enabled in SQL Server Configuration Manager
- Firewall rules for port 1433
- Databricks workspace with SQL endpoint
- Personal access token generated
- SQL endpoint running (not terminated)
- Appropriate permissions on catalog/schema
Step 1: Install ingestr
Install ingestr in seconds using pip. Choose the method that works best for you:
Recommended: Using uv (fastest)
# Install uv first if you haven't already
pip install uv
# Run ingestr using uvx
uvx ingestr
Alternative: Global installation
# Install globally using uv
uv pip install --system ingestr
# Or using standard pip
pip install ingestr
Verify installation: Run ingestr --version
to confirm it's installed correctly.
Step 2: Your First Migration
Let's copy a table from Microsoft SQL Server to Databricks. This example shows a complete, working command you can adapt to your needs.
Set up your connections
Microsoft SQL Server connection format:
mssql://username:password@host:port/database
Parameters:
- • username: SQL Server login
- • password: Login password
- • host: Server name or IP
- • port: Port number (default 1433)
- • database: Database name
- • encrypt: Use encryption (true/false)
- • trustServerCertificate: Trust certificate
Databricks connection format:
databricks://token@host:port/http_path
Parameters:
- • token: Personal access token (use as username)
- • host: Workspace URL
- • port: Port number (usually 443)
- • http_path: SQL endpoint HTTP path
BigQuery Setup Required
Before running the command:
- Create a service account in Google Cloud Console
- Grant it BigQuery Data Editor and Job User roles
- Download the JSON key file
- Use the path to this file in your connection string
Run your first copy
Copy the entire users table from Microsoft SQL Server to Databricks:
ingestr ingest \
--source-uri 'mssql://sa:MyPass123@localhost:1433/AdventureWorks' \
--source-table 'dbo.Customers' \
--dest-uri 'databricks://[email protected]:443/sql/1.0/endpoints/abc123' \
--dest-table 'raw.Customers'
What this does:
- • Connects to your Microsoft SQL Server database
- • Reads all data from the specified table
- • Creates the table in Databricks if needed
- • Copies all rows to the destination
Command breakdown:
--source-uri
Your source database--source-table
Table to copy from--dest-uri
Your destination--dest-table
Where to write data
Step 3: Verify your data
After the migration completes, verify your data was copied correctly:
Check row count in Databricks:
-- Run this in Databricks
SELECT COUNT(*) as row_count
FROM raw.Customers;
-- Check a sample of the data
SELECT *
FROM raw.Customers
LIMIT 10;
Advanced Patterns
Once you've mastered the basics, use these patterns for production workloads.
Only copy new or updated records since the last sync. Perfect for daily updates.
ingestr ingest \
--source-uri 'mssql://sa:MyPass123@localhost:1433/AdventureWorks' \
--source-table 'public.orders' \
--dest-uri 'databricks://[email protected]:443/sql/1.0/endpoints/abc123' \
--dest-table 'raw.orders' \
--incremental-strategy merge \
--incremental-key updated_at \
--primary-key order_id
How it works: The merge strategy updates existing rows and inserts new ones based on the primary key. Only rows where updated_at
has changed will be processed.
Common Use Cases
Ready-to-use commands for typical Microsoft SQL Server to Databricks scenarios.
Daily Customer Data Sync
Keep your analytics warehouse updated with the latest customer information every night.
# Add this to your cron job or scheduler
ingestr ingest \
--source-uri 'mssql://sa:MyPass123@localhost:1433/AdventureWorks' \
--source-table 'public.customers' \
--dest-uri 'databricks://[email protected]:443/sql/1.0/endpoints/abc123' \
--dest-table 'analytics.customers' \
--incremental-strategy merge \
--incremental-key updated_at \
--primary-key customer_id
Historical Data Migration
One-time migration of all historical records to your data warehouse.
# One-time full table copy
ingestr ingest \
--source-uri 'mssql://sa:MyPass123@localhost:1433/AdventureWorks' \
--source-table 'public.transactions' \
--dest-uri 'databricks://[email protected]:443/sql/1.0/endpoints/abc123' \
--dest-table 'warehouse.transactions_historical'
Development Environment Sync
Copy production data to your development Databricks instance (with sensitive data excluded).
# Copy sample data to development
ingestr ingest \
--source-uri 'mssql://sa:MyPass123@localhost:1433/AdventureWorks' \
--source-table 'public.products' \
--dest-uri 'databricks://[email protected]:443/sql/1.0/endpoints/abc123' \
--dest-table 'dev.products' \
--limit 1000 # Only copy 1000 rows for testing
Troubleshooting Guide
Solutions to common issues when migrating from Microsoft SQL Server to Databricks.
Connection refused or timeout errors
Check your connection details:
- Enable TCP/IP in SQL Server Configuration Manager
- Check SQL Server Browser service is running
- Verify Windows Firewall allows SQL Server
- Ensure Mixed Mode authentication if using SQL login
- Ensure SQL endpoint is running
- Verify personal access token is valid
- Check workspace URL is correct
- Confirm HTTP path matches your endpoint
Authentication failures
Common authentication issues:
- Enable TCP/IP in SQL Server Configuration Manager
- Check SQL Server Browser service is running
- Verify Windows Firewall allows SQL Server
- Ensure Mixed Mode authentication if using SQL login
- Ensure SQL endpoint is running
- Verify personal access token is valid
- Check workspace URL is correct
- Confirm HTTP path matches your endpoint
Schema or data type mismatches
Handling data type differences:
- ingestr automatically handles most type conversions
- Microsoft SQL Server: NVARCHAR for Unicode support
- Microsoft SQL Server: Hierarchyid for tree structures
- Microsoft SQL Server: Spatial data types for geographic data
- Microsoft SQL Server: XML and JSON support
- Databricks: Delta tables support schema evolution
- Databricks: Complex types (arrays, maps, structs) supported
- Databricks: Photon acceleration for certain operations
- Databricks: Partitioning affects query performance
Performance issues with large tables
Optimize large data transfers:
- Use incremental loading to process data in chunks
- Run migrations during off-peak hours
- Split very large tables by date ranges using interval parameters
