The Connect CDC (SQData) enterprise data integration product utilizes a four part framework; Capture, transient storage, Publisher and the Apply Engine. UDB changed data is retrieved from the recovery logs by the Log Reader based on requests from the Publisher. Memory mapped storage is then used by the Store and the Publisher to avoid "landing" the data. The Publisher uses TCP/IP to transport captured data and ensures that the Store "discards" data upon confirmation that a Unit-of-work has been committed by all subscribing Apply Engines.
