Migrate MySQL to Amazon Redshift in 60 Seconds
Learn how to copy your MySQL data to Amazon Redshift with a single command using ingestr - no code required.
What you'll learn
Prerequisites
- Python 3.8 or higher installed
- MySQL server running and accessible
- User with appropriate GRANT permissions
- Database exists or permission to create
- Network access to MySQL port
- Redshift cluster running and accessible
- Security group allows inbound connections
- Database user with appropriate permissions
- VPC and subnet properly configured
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 MySQL to Amazon Redshift. This example shows a complete, working command you can adapt to your needs.
Set up your connections
MySQL connection format:
mysql://username:password@host:port/database
Parameters:
- • username: MySQL user
- • password: User password
- • host: Server hostname or IP
- • port: Server port (default 3306)
- • database: Database name
- • charset: Optional character set
Amazon Redshift connection format:
redshift://username:password@host:port/database
Parameters:
- • username: Master username or IAM user
- • password: User password
- • host: Cluster endpoint URL
- • port: Port number (default 5439)
- • database: Database name
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 MySQL to Amazon Redshift:
ingestr ingest \
--source-uri 'mysql://root:password@localhost:3306/myapp' \
--source-table 'users' \
--dest-uri 'redshift://admin:[email protected]:5439/mydb' \
--dest-table 'raw.users'
What this does:
- • Connects to your MySQL database
- • Reads all data from the specified table
- • Creates the table in Amazon Redshift 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 Amazon Redshift:
-- Run this in Amazon Redshift
SELECT COUNT(*) as row_count
FROM raw.users;
-- Check a sample of the data
SELECT *
FROM raw.users
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 'mysql://root:password@localhost:3306/myapp' \
--source-table 'public.orders' \
--dest-uri 'redshift://admin:[email protected]:5439/mydb' \
--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 MySQL to Amazon Redshift 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 'mysql://root:password@localhost:3306/myapp' \
--source-table 'public.customers' \
--dest-uri 'redshift://admin:[email protected]:5439/mydb' \
--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 'mysql://root:password@localhost:3306/myapp' \
--source-table 'public.transactions' \
--dest-uri 'redshift://admin:[email protected]:5439/mydb' \
--dest-table 'warehouse.transactions_historical'
Development Environment Sync
Copy production data to your development Amazon Redshift instance (with sensitive data excluded).
# Copy sample data to development
ingestr ingest \
--source-uri 'mysql://root:password@localhost:3306/myapp' \
--source-table 'public.products' \
--dest-uri 'redshift://admin:[email protected]:5439/mydb' \
--dest-table 'dev.products' \
--limit 1000 # Only copy 1000 rows for testing
Troubleshooting Guide
Solutions to common issues when migrating from MySQL to Amazon Redshift.
Connection refused or timeout errors
Check your connection details:
- Check bind-address in my.cnf (should not be 127.0.0.1 for remote)
- Verify user has permission from connecting host
- Ensure port 3306 is not blocked by firewall
- Test with mysql client to isolate issues
- Verify cluster is not paused
- Check VPC security group rules
- Ensure cluster is publicly accessible if connecting from outside VPC
- Validate IAM roles if using temporary credentials
Authentication failures
Common authentication issues:
- Check bind-address in my.cnf (should not be 127.0.0.1 for remote)
- Verify user has permission from connecting host
- Ensure port 3306 is not blocked by firewall
- Test with mysql client to isolate issues
- Verify cluster is not paused
- Check VPC security group rules
- Ensure cluster is publicly accessible if connecting from outside VPC
- Validate IAM roles if using temporary credentials
Schema or data type mismatches
Handling data type differences:
- ingestr automatically handles most type conversions
- MySQL: JSON type available in MySQL 5.7+
- MySQL: DATETIME vs TIMESTAMP timezone handling
- MySQL: Character set and collation settings
- MySQL: Strict mode affects data validation
- Amazon Redshift: SUPER type for semi-structured data
- Amazon Redshift: SORTKEY and DISTKEY affect performance
- Amazon Redshift: VARCHAR length limits are enforced
- Amazon Redshift: Compression encodings impact storage
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
