Database physical design refinement using a merge-reduce approach

摘要

Various embodiments are disclosed relating to database configuration refinement. In an example embodiment, a method is provided that may include determining a size limitation for a database configuration, determining a workload of the database configuration, and making a determination that a size of the database configuration is greater than a size limit. The method may also include applying either a merge process or a reduction process to decrease the size of the database configuration. The merge process may merge a first index/view with a second index/view to produce a merged index/view, for example. The reduction process may delete a first portion of a first view to produce a reduced view.
