Evidence boundary: The case establishes the analytical warehouse migration, not replacement of Verihubs' operational PostgreSQL systems.

What was reported

Verihubs moved from a PostgreSQL warehouse populated through daily Airflow pulls to ClickHouse with change-data-capture ingestion and real-time analytical processing.

Verified facts

  • The source warehouse used PostgreSQL and batch ingestion.
  • ClickHouse is the destination OLAP platform.
  • Reporting, reconciliation and invoicing analytics are in scope.
  • The migration took approximately six months.

What is not established

  • Retirement of PostgreSQL from transactional applications.
  • The complete source-system inventory.
  • The exact final production cutover date.

PlatformTrace analysis

This is a clear architecture change from a batch relational warehouse to a real-time columnar OLAP platform. The scope is analytical and should not be broadened to all PostgreSQL use.
