Design and develop streaming ingestion pipelines using Apache Spark (Structured Streaming) and Databricks Auto Loader to consume files from cloud storage or messages from Kafka/RabbitMQ/Confluent Cloud and ingest them into Delta Lake, ensuring schema evolution and exactly once semantics. Implement CDC and deduplication logic by capturing change events from source databases using Debezium, built‑in CDC features of SQL Server/Oracle, or other connectors, and apply watermarking and drop duplicate strategies based on primary keys and event timestamps. Scale ingestion through configuration by building a config‑driven framework such as using Airflow, DBX Jobs, or Delta Live Tables that iterates over metadata tables to deploy/update ingestion pipelines for hundreds of tables/sources without code duplication. Implement monitoring, observability, and security by capturing streaming query metrics and publishing them to monitoring platforms like Prometheus and Grafana, setting up dashboards fo...
