Design a scalable PII detection and remediation system that scans structured and unstructured datasets, flags probable PII exposures, and automates quarantining or redaction workflows. Requirements: handle petabyte-scale data, low false positive rate, integration with CI/CD and metadata catalog, and maintain audit trails for compliance. Describe architecture, algorithms, and operational workflow.

Design monitoring and alerting for Kafka-based data pipelines handling roughly 1,000 topics and thousands of partitions. Requirements: detect consumer lag, message loss, transformation errors, and stalled connectors; route alerts to topic owners; and minimize false positives. Sketch a scalable architecture, list the key metrics you would collect, and outline alerting strategy.
