Redshift Vault Configuration

Redshift vaults provide secure access to Amazon Redshift clusters, enabling comprehensive data quality monitoring for your cloud data warehouse.

Overview​

Amazon Redshift is a fully managed, petabyte-scale data warehouse service in the cloud. DeepDQ's Redshift vault integration supports both provisioned clusters and serverless workgroups, providing robust data quality monitoring across your Redshift environment.

Configuration Parameters​

Required Fields​

  • Name: A unique identifier for your Redshift vault
  • Type: Redshift (automatically selected)
  • Host: The Redshift cluster endpoint or serverless workgroup endpoint
  • Port: The port number (default: 5439)
  • Database: The database name in Redshift
  • User: Your Redshift username
  • Password: Your Redshift password (securely encrypted)

Example Configuration​

Name: Production Redshift Vault
Type: Redshift
Host: your-cluster.region.redshift.amazonaws.com
Port: 5439
Database: your_database
User: your_username
Password: [encrypted]

Redshift Deployment Types​

Provisioned Clusters​

Traditional Redshift clusters with dedicated compute resources:

  • Predictable performance and costs
  • Manual scaling and maintenance
  • Full control over cluster configuration
  • Ideal for consistent, high-volume workloads

Redshift Serverless​

Automatically scaling serverless data warehouse:

  • Pay-per-use pricing model
  • Automatic scaling based on workload
  • No cluster management required
  • Ideal for variable or unpredictable workloads

Authentication Methods​

Database User Authentication​

  • Standard Redshift username and password
  • Database-specific user accounts
  • Password-based authentication
  • Currently supported by DeepDQ

Connection Requirements​

Network Access​

  • Ensure connectivity to Redshift cluster/workgroup
  • Configure VPC security groups and routing
  • Set up appropriate firewall rules
  • Consider VPC endpoints for private connectivity
  • DeepDQ Static IP: Contact salesandsupport@deepanalyze.ai to get the Static IP for whitelisting

Database Permissions​

The Redshift user requires these minimum privileges:

  • CONNECT privilege on the database
  • SELECT privilege on tables to be monitored
  • USAGE privilege on schemas containing monitored tables

Example privilege grants:

GRANT CONNECT ON DATABASE your_database TO deepdq_user;
GRANT USAGE ON SCHEMA public TO deepdq_user;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO deepdq_user;

Common Use Cases​

Troubleshooting​

Connection Issues​

Cluster Connectivity Problems

  • Verify cluster endpoint and port configuration
  • Check VPC security groups and network ACLs
  • Validate DNS resolution for cluster endpoint
  • Ensure cluster is in available state

Authentication Failures
