Feb 1, 2025February 2025: Key API, schema, and stability enhancements across Embucket/embucket. Delivered a backward-compatible query API overhaul with FQN-based warehouse inference and a new /ui/query endpoint, enabling scalar functions and cross-endpoint compatibility while preserving older routes. Added CREATE SCHEMA support via enhanced table path parsing and tests. Consolidated workspace dependencies and pinned build/tooling to ensure consistent DataFusion and iceberg-rust versions, improving build reliability. Fixed critical dbt/HTTP error handling, improved login filtering by database_name, and tightened Arrow data types and session handling for correctness. Result: stronger multi-tenant data capabilities, faster debugging, and more reliable operations across the stack.
