It can be used in 2 modes: PUSH and PULL modes.

  • PUSH – changes are published as it happens
  • PULL – changes are captures at regular intervals – say once a day or every 5 minutes

CDC uses the native services of the database architecture, adheres to the database vendor’s documented formats and APIs, and minimizes the invasive impact on any operational systems.
