Abstract

See full text

A method and system for managing attributes in a streaming application is disclosed. The system may have a stream manager communicatively coupled with processing elements for tracking a stream of tuples. The system may also have a first stream operator communicatively coupled with the stream manager and capable of receiving the stream of tuples, wherein the first stream operator selects the selected attribute of the first tuple and assigns a first identifier to the selected attribute. The system may also have a second stream operator communicatively coupled with the stream manager and capable of receiving the stream of tuples, and capable of replacing the selected attribute in the second tuple with a second identifier provided by the first stream operator. The system may also have an identifier table communicatively coupled with the stream manager and the first and second stream operator, wherein the identifier table includes identifiers for selected tuples.
