What prerequisites are needed to connect ParadeDB to Tableau?

Install ParadeDB (a PostgreSQL-compatible extension) and confirm it listens on a routable host:port. Create a least-privilege Tableau user with SELECT rights on target schemas. Download and install the latest Tableau Desktop or Tableau Cloud driver for PostgreSQL if prompted.

Which connector do I choose in Tableau?

Select “PostgreSQL” under “To a Server.” ParadeDB exposes a standard PostgreSQL endpoint, so no custom driver is required.Leave “Require SSL” checked if ParadeDB enforces TLS.

How do I enter the ParadeDB connection details?

Fill in Host, Port (default 5432), Database, Username, and Password. For SSL, choose “Require.” Click “Sign In” to establish the session. Tableau lists available schemas and tables from ParadeDB.

Can I use custom SQL to optimize queries?

Yes. Click “New Custom SQL,” then paste optimized statements that exploit ParadeDB’s vector search or materialized views.This pushes heavy computation to ParadeDB and speeds dashboards.

How do I visualize ecommerce metrics?

Drag Orders.total_amount to “Rows,” order_date to “Columns,” and set aggregation to SUM to plot revenue trends.Leverage Tableau calculations while keeping raw data in ParadeDB.

How can I publish the data source for others?

After building the workbook, choose “Server → Publish Data Source.” Enter ParadeDB credentials with an embedded password so Tableau Server refreshes extracts on schedule.

Best practices for ParadeDB + Tableau

• Limit extracts; use Live mode to keep dashboards current.
• Index frequently filtered columns in ParadeDB.
• Create materialized views for heavy joins.
• Monitor ParadeDB query logs to fine-tune slow visuals.

Common Mistakes

Using the wrong port. Some ParadeDB installs run on 6432; Tableau fails to connect. Always confirm SHOW port; or check parade.conf and update Tableau accordingly.
Disabling SSL for convenience. This exposes credentials in transit. Instead, enable SSL on ParadeDB and choose “Require” in Tableau to encrypt traffic.
