20 Commits • 3 Features
Oct 1, 2025October 2025 monthly summary for IBM/data-prep-kit: Delivered three major, cross-cutting enhancements across the OpenSearch-enabled data processing workflow, focusing on local development/testing reliability, vector search capabilities, and unified logging. The work reduces local setup friction, accelerates validation of features, and improves observability and diagnostics across pipelines. Key outcomes include a Docker Compose-based OpenSearch local environment using OpenSearch 3.2.0, jVector integration with parameterized transforms, and a unified logging framework with JSON-formatted logs and enhanced subprocess visibility. Tests and documentation were updated to reflect new capabilities, including safeguards for data directories and health-check timeouts, as well as additional logging diagnostics.
