Techniques for sorting a sequence of one or more input objects are provided. The techniques include identifying a property that is exhibited by a sequence of one or more input objects, determining whether each input object from the sequence of one or more input objects exhibits the property, storing each of the one or more input objects into a buffer, wherein an input object is stored in a first buffer if it exhibits the property and an input object is stored in a second buffer if it does not exhibit the property, sorting each of the one or more input objects in each buffer, and merging the one or more input objects in each buffer into a sequence of one or more input objects.
