3 Commits • 1 Features
Oct 1, 2025In 2025-10, focused on stabilizing the MAG data processing pipeline by integrating SCLK dependencies (SPICE), updating configurations, improving test coverage for L1C SPICE paths, and performing routine release engineering to bump sds-data-manager to 9.0.1. These efforts reduce data-processing risk, accelerate release readiness, and improve overall maintainability.

Jun 1, 2025June 2025 monthly summary for IMAP-Science-Operations-Center/sds-data-manager. Delivered a coherent set of features that strengthen data processing configuration, pipeline determinism, and data governance, while expanding test coverage and hardening the system against config drift. Key outcomes include improved dependency configuration management for l2 processing levels (leapseconds and spacecraft_clock) with SPICE-related test coverage, enabling more reliable data fusion timing; a Glows dataset dependency configuration to ensure L1B→L2 progression with HARD triggers and downstream dependencies; expanded S3 object tagging to support metadata tagging across data buckets via GetObjectTagging and PutObjectTagging with updated IAM policies; and BatchStarter robustness improvements introducing delayed SQS queues, multi-queue handling, updated queue URL logic, and broader test coverage for multi-queue scenarios. These changes collectively reduce configuration drift, increase pipeline determinism, and enhance data governance. Technologies/skills demonstrated include AWS IAM/S3 tagging, SQS-based orchestration, SPICE/test coverage integration, configuration management for data processing pipelines, and targeted test expansion to validate multi-queue scenarios.
