A system and method for modifying the processing within a streaming application are disclosed. The method may include identifying a grouping location at which it may be possible to group tuples during the runtime execution of a streaming application. In some embodiments, this may include identifying locations at which a runtime grouping condition may be added to one or more stream operators without adversely affecting the performance of a streaming application. The method may add a runtime grouping condition to a processing location within the plurality of stream operators of a streaming application, in some embodiments.
