Query Spice.ai using Tableau

Announcing the release of Spice v1.1.2! 🔗

Spice v1.1.2 improves Delta Lake Data Connector performance, introduces new Accept headers for the /v1/sql and /v1/nsql endpoints to include query metadata with results, and resolves an issue with the Snowflake Data Connector when handling wide tables (>600 columns).

The official Tableau Connector for Spice.ai v0.1 has been released, making it easy to connect to both self-hosted Spice.ai and Spice Cloud instances using Tableau.

What's New in v1.1.2​

  • Tableau Connector for Spice.ai: Released the initial version (v0.1) of the official Tableau Taco Connector (fully open-source), enabling data visualization and analytics in Tableau with self-hosted Spice.ai and Spice Cloud deployments.

  • Delta Lake Data Connector: Upgraded delta_kernel to v0.9, and optimized scan operations, reducing query execution time by up to 20% on large datasets.

  • Snowflake Data Connector: Fixed a bug that caused failures when loading tables with more than 600 columns.

  • Query Metadata (SQL and NSQL): Added support for the application/vnd.spiceai.sql.v1+json Accept header on the /v1/sql endpoint, and the application/vnd.spiceai.nsql.v1+json Accept header on the /v1/nsql endpoint, enabling responses to include metadata such as the executed SQL query and schema alongside results.

Example:

curl -XPOST "http://localhost:8090/v1/nsql" \
  -H "Content-Type: application/json" \
  -H "Accept: application/vnd.spiceai.nsql.v1+json" \
  -d '{
    "query": "What’s the highest tip any passenger gave?"
  }' | jq

Example response:

{
  "row_count": 1,
  "schema": {
    "fields": [
      {
        "name": "highest_tip",
        "data_type": "Float64",
        "nullable": true,
        "dict_id": 0,
        "dict_is_ordered": false,
        "metadata": {}
      }
    ],
    "metadata": {}
  },
  "data": [
    {
      "highest_tip": 428.0
    }
  ],
  "sql": "SELECT MAX(\"tip_amount\") AS \"highest_tip\"\nFROM \"spice\".\"public\".\"taxi_trips\""
}

For details, see the SQL Query API and NSQL API documentation.
