MANAGEMENT OF STREAM OPERATORS WITH DYNAMIC CONNECTIONS

摘要

One embodiment is directed to a method for processing a stream of tuples in a stream-based application. A stream operator may receive a stream of tuples. A stream manager may determine whether a dynamic connection exists at a first stream operator. The dynamic connection may connect the first stream operator to a second stream operator. The stream manager may poll the first stream operator and the second stream operator for a presence of the dynamic connection. The stream manager may modify processing of one or more upstream stream operators in response to a change in use of the dynamic connection.

1. A method for processing a stream of tuples, comprising:
receiving a stream of tuples to be processed by a plurality of processing elements operating on one or more computer processors, each processing element having one or more stream operators; determining whether a dynamic connection exists at a first stream operator, wherein the dynamic connection connects the first stream operator to a second stream operator; and modifying processing of the stream of tuples in response to a condition.
