Event-driven airline data ingestion pipeline orchestrating CSV uploads through S3, EventBridge, and Step Functions to validate and transform flight data across multi-AZ Glue ETL jobs. Data flows from S3 uploads through EventBridge triggers into Step Functions, which coordinates parallel Glue ETL jobs in separate availability zones for validation and transformation. The architecture writes clean data to RDS Primary with standby failover, routes errors to S3, and sends pipeline alerts via SNS to operations teams.
