Unlocking real-time analytics: Streaming Aurora DSQL changes into Apache Iceberg

A walkthrough demonstrates streaming Amazon Aurora DSQL change data capture (CDC) events into Apache Iceberg tables stored on Amazon S3 via Amazon Data Firehose, queryable through Amazon Athena. The design uses two Iceberg tables: an append-only cdc_events audit trail ordered by transaction commit timestamp, and a current_state table that merges rows by primary key with tombstone flags for deletes. It covers handling out-of-order CDC delivery, reconstructing a strictly correct current state from cdc_events, deployment via a CloudFormation stack, and exploring results with a Streamlit dashboard.
