3 Commits • 3 Features
Feb 1, 2026February 2026 (2026-02): Delivered three focus features in arthur-engine with strong business value: analytics enrichment, secure connectivity, and data flexibility. Implemented the Daily Analytics Endpoint for Agentic Annotations to enable daily-pass/fail/skip metrics retrieval within a specified window; extended the Databricks connector to support IDA AWS token exchange, adding new configuration and token-exchange logic for secure, token-based authentication; added support for static datasets without time columns by bypassing time-based filtering and ensuring full data retrieval, including validation tests.
