Redshift Integration

​

Overview

• Intelligent SQL Querying - AI-powered query optimization and result analysis
• Advanced Schema Inspection - Comprehensive table structure analysis and documentation
• Smart Column Discovery - Efficient data exploration and column-based searches
• Cost-Effective Operations - Read-only access to prevent accidental data modifications
• Performance Optimization - Query performance insights and optimization recommendations
• Safe Operations - All tools are read-only for maximum data security

​

Key Capabilities

​

Prerequisites

• Amazon Redshift cluster with network accessibility
• Database credentials with read access permissions
• Redshift connection string or connection parameters
• Calmo account with team or personal workspace

​

Setup Process

​

Step 1: Prepare Redshift Access

1. Identify your Redshift cluster endpoint
2. Note the database name, port, and region
3. Ensure network security groups allow connections from Calmo
4. Verify SSL/TLS configuration if required

postgresql://username:password@host:port/database

postgresql://analytics_user:password123@my-cluster.abc123.us-east-1.redshift.amazonaws.com:5439/analytics_db

​

Step 2: Create Database User (Recommended)

-- Create a dedicated user for Calmo integration
CREATE USER calmo_user PASSWORD 'secure_password_here';

-- Grant necessary permissions for read-only access
GRANT USAGE ON SCHEMA public TO calmo_user;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO calmo_user;

-- Grant permissions for schema inspection
GRANT USAGE ON SCHEMA information_schema TO calmo_user;
GRANT SELECT ON ALL TABLES IN SCHEMA information_schema TO calmo_user;

-- For specific schemas, replace 'public' with your schema names
GRANT USAGE ON SCHEMA your_schema_name TO calmo_user;
GRANT SELECT ON ALL TABLES IN SCHEMA your_schema_name TO calmo_user;

• Use a dedicated user account for the integration
• Grant only necessary read permissions
• Use strong passwords and rotate them regularly
• Consider using IAM authentication for enhanced security

​

Step 3: Connect to Calmo

1. Navigate to Integrations in your Calmo dashboard
2. Click Redshift integration
3. Enter your Connection String (including credentials)
4. Configure tool permissions:
   • ✅ All operations are read-only by design
   • ✅ All tools enabled by default for comprehensive data access
5. Test the connection using the built-in connection test
6. Complete the integration setup

​

Tool Categories & Configuration

​

Querying (Safe)

• redshift_query - Execute read-only SQL queries against your Redshift data warehouse

​

Schema Inspection (Safe)

• redshift_describe_table - Get detailed information about a specific table including columns, types, and constraints

​

Column Search (Safe)

• redshift_find_column - Find tables containing columns with specific name patterns

​

Team vs Personal Configuration

​

Team/Organization Setup

• Shared Redshift cluster access across team members
• Organization-level data governance and access policies
• Centralized query execution and analysis workflows
• Team-wide data insights and reporting capabilities

​

Personal Setup

• Individual Redshift cluster connections
• Personal data analysis and exploration
• Private query development and testing
• Individual data discovery and research

​

Security & Best Practices

​

⚠️ Safety Recommendations

1. Read-Only Access - All tools are read-only by design for maximum security
2. Dedicated User - Use a dedicated database user for the integration
3. Minimal Permissions - Grant only necessary read permissions to required schemas
4. Connection Security - Use SSL/TLS encryption for database connections
5. Network Security - Ensure proper security group and firewall configurations

​

🔒 Permission Levels

​

Configuration Management

​

Updating Redshift Connection

1. Navigate to Integrations → Redshift
2. Click Edit Configuration
3. Update connection string if credentials or endpoint change
4. Test connection to verify changes
5. Save configuration updates

​

Managing Multiple Clusters

• Connect separate Redshift clusters for different environments
• Use different database users for production vs development
• Configure environment-specific data access policies
• Maintain separate analytics workflows per cluster
