Adaptive experience based De-duplication
Example apparatus and methods associated with adaptive experience based de-duplication are provided. One example data de-duplication apparatus includes a de-duplication logic, an experience logic, and a reconfiguration logic. The de-duplication logic may be configured to perform data de-duplication according to a configurable approach that is a function of a pre-defined constraint. The experience logic may be configured to acquire de-duplication performance experience data. The reconfiguration logic may be configured to selectively reconfigure the configurable approach on the apparatus as a function of the de-duplication performance experience data. In different examples, dynamic reconfiguration may be performed locally and/or in a distributed manner based on local and/or distributed data that is acquired on a per actor (e.g., user, application) basis and/or on a per entity (e.g., computer, data stream) basis.
