11 Commits • 3 Features
Oct 1, 2025October 2025: In atlanhq/atlas-metastore, delivered critical data quality and reliability improvements with a focus on type validation, operational isolation, and resilient graph metadata handling. Notable outcomes include robust Atlas string type validation with rollback for new attributes, safer soft-reference handling, audit/search isolation on the write cluster, more fault-tolerant typedef refresh across Atlas instances, and strengthened null-safety and observability for graph retrieval and time-related fields. These work items reduce data defects, prevent crashes, and simplify incident debugging while improving deployment resilience in Kubernetes, Elasticsearch, and Graph services.

Aug 1, 2025During August 2025, the atlas-metastore work delivered a robust CI/build setup, data quality improvements, and stability/observability enhancements across the data pipeline. Key outcomes include a dedicated build branch and workflow; MLH-965 entity enrichment prior to Kafka; removal of circular dependency; build branch integration; and synchronization with the latest staging to maintain compatibility. DSL/ES improvements (regex simplification and wildcard consolidation) reduced complexity and tightened validations. Enhanced error handling with 410 on permanent backend errors; observability enhancements for tag propagation; read-after-write consistency for SDKs/workflows; and updates to Kafka notification handling (updateTime/updatedBy). Defaults were added for missing attributes and the removePropagationsOnEntityDelete flag. Asset affected counts are now correct. These changes improve reliability, data correctness, developer velocity, and overall business trust in real-time data feeds.
