Abstract
Feedback tuples are implemented in a stream computing environment to provide data flow status information for use in detecting, identifying and/or handling data flow anomalies for a stream computing application.
Claims20
A method for processing a stream of tuples in a stream computing environment, the method comprising:
- processing, in a first stream operator among a plurality of stream operators, a plurality of data tuples;
- and
- issuing a negative feedback tuple to an upstream entity in response to detecting a data flow anomaly of a data flow between the first stream operator and the upstream entity.
An apparatus comprising:
- one or more processing devices and a memory device operably coupled to the one or more processing devices, the one or more processing devices are configured to:
- process, in a first stream operator among a plurality of stream operators, a plurality of data tuples;
- and
- issue a negative feedback tuple to an upstream entity in response to detection of a data flow anomaly of a data flow between the first stream operator and the upstream entity.
1 more element
A computer program product, the computer program product comprising:
- one or more computer readable storage media;
- and
- program instructions collectively stored on the one or more computer readable storage media, the program instructions comprising:
- program instructions to process, in a first stream operator among a plurality of stream operators, a plurality of data tuples;
- and
- program instructions to issue a negative feedback tuple to an upstream entity in response to detection of a data flow anomaly of a data flow between the first stream operator and the upstream entity.
