This module is responsible for providing with a datacentric (meaning decoupled and producer/consumer agnostic) abstraction on top of the :ref:`architecture_protocol`, which holds the memory used to maintain the necessary history caches.

.. important::

    In the current version of Safe DDS, the datacentric operation is not configurable by the user.
