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.
  • Official Release: github.com/spicehq/tableau-connector/releases/tag/v0.1.0
  • Docs: spiceai.org/docs/clients/tableau
  • Open Source Repository: github.com/spiceai/tableau-connector

• 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.
