WHC Blackwater Mine Unified Data Architecture ingests 6K PI Historian tags, Ampla IQT/DAS sheets, and Citect SCADA signals into an AWS data lake with dual hot and cold paths. The hot path streams ~200 records/second through Kinesis Data Streams to Lambda consumers, populating DynamoDB (P1 KPIs <10ms), Timestream (P2 Trends <2s), and EventBridge (P3 Recommendations <5s) for real-time dashboards. The cold path batches data via Kinesis Firehose into S3 Raw Zone, then Glue ETL curates 3.13B PI rows into Apache Iceberg tables, enabling Athena ad-hoc queries and SageMaker ML feature engineering. Step Functions orchestrates the entire pipeline while Lake Formation, IAM, and VPC enforce governance across Blackwater and future Daunia sites.
