Partner with Governance teams to ensure compliance with data lineage, cataloging, and security policies (e.g., Azure Purview).
Establish proactive monitoring and alerting mechanisms to identify and resolve pipeline or infrastructure issues.
Continuously tune and optimize pipelines and queries for performance, scalability, and cost efficiency.
Leverage Azure Monitor, Log Analytics, and Application Insights to track, troubleshoot, and enhance system performance.
