Cube Core releases v0.33.0 through v0.33.43 introduces two significant integrations: LangChain for building AI-based applications and DuckDB, a performant in-process SQL OLAP database management system, allowing users to easily query data stored in various formats such as Parquet, CSV, or JSON files at cloud storage servers like AWS S3, Google Cloud Storage, and Cloudflare R2. The running_total measure type is deprecated in favor of the rolling_window option, which provides more flexibility and general-purpose functionality. With these updates, Cube Core aims to provide a user-friendly and error-free access to data for builders of AI experiences.
