Database Connections

You can connect directly to your own databases—useful for building dashboards on custom applications, data warehouses, or legacy systems.

Supported databases

• PostgreSQL
• MySQL / MariaDB
• Microsoft SQL Server
• IBM DB2
• Snowflake — see the Snowflake setup guide

Prerequisites

You’ll need this info from your database administrator:

1. Host/IP: The server’s network address
2. Port: Connection port (e.g., 5432 for Postgres, 3306 for MySQL)
3. Database name: The specific schema to access
4. Read-only credentials: Username and password with SELECT permissions

Caution

Never use a superuser or admin account. Create a dedicated read-only user limited to the tables you need for reporting.

Setup instructions

Step 1: Whitelist our IPs

If your database is behind a firewall, you’ll need to whitelist our sync servers. Contact support@resplendentdata.com for the current IP list.

Step 2: Connect in Resplendent Data

1. Go to Settings → Integrations
2. Find your database type and click Connect on the card
3. Enter your connection details:
   • Host
   • Port
   • Database name
   • Username & password
   • Require SSL (off by default). Turn this on for cloud hosts that require encrypted connections, such as Supabase, Neon, or Amazon RDS.
4. Click Test Connection

Sync performance and refresh rates

Tier	Refresh frequency
Free Forever	Every 60 minutes
Starter	Every 15 minutes
Professional / Business / Starship	Every 60 seconds

Incremental sync

For larger tables, set up incremental sync to avoid pulling the entire table every time:

• Primary Key: The unique ID for each row
• Updated Column: A timestamp like updated_at that tells us which records changed

On-premise databases

If your database isn’t on the public internet, you can use the Resplendent Sync Agent (available on Business tier and higher).
