Abstract: Queries are monitored in a database which receives input from a stream computing application to identify data of interest. Parameters defining the data of interest, which are preferably expressed as a logical query, are sent to the stream computing application, which then processes the in-flight streamed data satisfying the parameters in some special manner. In some embodiments, the stream computing application increases the processing priority of in-flight data satisfying the parameters. In some embodiments, the stream computing application applies additional processing steps to the in-flight data satisfying the parameters to provide enhanced data or metadata.

The state data can be loaded into a local instance of the operator loaded into a debugger. At least a portion of the call graph can be presented to a user, and a flow of the tuple through the call graph based on the state data for the operator can be indicated.

Abstract: A database which receives input from a data streaming application may include in-flight streamed data within the scope of a command which alters database data. Preferably, the streaming application produces data tuples for input to at least one table of the database. A user submitting modify data commands to apply to multiple tuples meeting some specified logical parameters may define the command scope to include in-flight data in the streaming application, causing the database manager to forward the command to the streaming application. A streaming application manager invokes database agents in respective nodes of the streaming application, which identify in-flight data meeting the specified logical parameters of the command, and apply the modify data operation to such data.

Abstract: A tuple testing and routing operator in a streaming application routes data tuples to multiple parallel test operators that test in parallel the data tuples, receives feedback from the multiple parallel test operators regarding the results of testing the data tuples, routes a data tuple to a first operator when the data tuple passes the multiple parallel test operators according to a specified pass threshold, and optionally routes the data tuple to a second operator when the data tuple does not pass the multiple parallel test operators according to the specified pass threshold. The pass threshold allows testing to be done in a way that does not require all tests to be performed for all data tuples, thereby enhancing performance.

Abstract: In preventing malicious operator placement in a streaming application, a stream computing management system receives a submission of an operator graph for the streaming application. A scheduler of the stream computing management system places the operators across a plurality of computing nodes. A threat detector of the stream computing management system monitors placements of the operators during the submission of the operator graph and a runtime of the streaming application. The threat detector further monitors runtime activities of the operators of the streaming application. The threat detector compares the runtime activities of the operators of the streaming application with stored activities patterns. The threat detector determines whether any anomalies identified based on the comparing exceeds a risk tolerance threshold. In response to an anomaly exceeding the risk tolerance threshold, the scheduler changes a placement of at least one of the operators.
