Mar 1, 2025In March 2025, NEON-IS-data-processing delivered a set of stability, scalability, and data-quality enhancements across the data pipeline. Key features included generalized TChain for broader compatibility, upgrades to GCS-based data loaders with a v2 path and prod-bucket pulls, and data model/schema improvements. CI/CD was modernized with a build-push-update-action migration and expanded container publishing (GitHub Container Registry and GitHub Image Registry). Major bug fixes improved timestamp alignment, Kafka loader logging and event handling, and MDP record deletion/publishing logic. These changes increased reliability, reduced downstream failures, and accelerated data delivery to downstream consumers.

Feb 1, 2025February 2025 performance highlights for NEON-IS-data-processing: Delivered a modernization of the data pipeline with updated container images, addition of a compactor component, and newer Trino loader image to improve reliability and performance. Implemented end-to-end calibration with Kafka compactor across all source types and applied --alignperiod for consistent timing in Trino loader. Strengthened data quality and lineage through robust source type parsing, extensive date handling improvements, and extracting source IDs from bucket paths for accurate data provenance. Improved data governance and discoverability by attaching parquet metadata to outputs. Increased operational efficiency and cost control with an L0 bucket cleanup pipeline, narrowed data loading windows, and a move from DEBUG to INFO logging to reduce noise. Site list corrections, resource adjustments, and additional configuration options (bucket version path and path indices arguments) further supported stability and flexibility. These changes collectively increase data reliability, reduce operational overhead, and enable scalable growth.
