  • Variable checkpointing in a streaming application that includes tuple windows
    Patent number: 10375137
    Abstract: A variable checkpoint mechanism in a streams manager checkpoints a streaming application based on periodic time periods for checkpoints. The variable checkpoint mechanism can take a checkpoint early before a periodic time period ends or late after the periodic time period ends based on predicted size of one or more tuple windows in the streaming application. The time for taking the checkpoint can be selected based on multiple checkpoint timing criteria, which include storage requirement for the checkpoint and predicted backpressure in the flow graph. In this manner the checkpoint timing of the variable checkpoint mechanism can be adjusted real-time to minimize the negative impact of checkpointing on the performance of the streaming application.

  • DATA ANALYSIS IN STREAMING DATA
    Publication number: 20190236283
    Abstract: A method for data analysis in streaming data includes receiving a stream of data, the stream of data including ordered compressed files. The method may also include partitioning the stream of data into portions of the ordered compressed files. The method may also include concurrently filtering each of the portions of ordered compressed files with a filter. The method may further include forward matching portions of the ordered compressed files downstream of the received stream of data.

  • Managing the Processing of Streamed Data in a Data Streaming Application Using Query Information from a Relational Database
    Publication number: 20190235919
    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.

  • Variable checkpointing in a streaming application with one or more consistent regions
    Patent number: 10360109
    Abstract: A variable checkpoint mechanism in a streams manager checkpoints a streaming application based on periodic time periods for checkpoints. The variable checkpoint mechanism can take a checkpoint before a periodic time period ends when a spike is coming, or can take a checkpoint after the periodic time period ends when there is backpressure in a consistent region of the streaming application. When there is no anticipated spike coming and when there is no backpressure in a consistent region of the streaming application, the checkpoint is performed at the normal end of the periodic time period for checkpoints. In this manner the checkpoint timing of the variable checkpoint mechanism can be adjusted real-time to minimize the negative impact of checkpointing on the performance of the streaming application.

  • Debugging a live streaming application
    Patent number: 10353802
    Abstract: A connection can be made to a processing element of a remotely deployed and live streaming application executed by a first data processing system, the processing element containing at least one operator that processes at least one tuple. As the live streaming application is executed, without slowing or modifying data flow of the live streaming application execution to client devices, a copy of the tuple and a memory dump of state data for a state of the operator can be received, and the tuple can be tracked through a call graph. 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.

  • Splitting operators in a streaming application
    Patent number: 10353677
    Abstract: An operator split mechanism analyzes code in a streaming application according to specified split criteria to determine when an operator in the streaming application can be split. At compile-time, when an operator satisfies the split criteria, the operator split mechanism splits the operator according to the split criteria. In an integrated development environment (IDE), the operator split mechanism determines when an operator satisfies the split criteria, and splits the operator according to the split criteria. The operator split mechanism can operate in an automatic mode where operators are split without further input from the user, or in a more interactive mode where the operator split mechanism provides recommendations and options to a user, who makes appropriate selections, and the operator split mechanism then functions according to the selections by the user.

  • Data tuple testing and routing for a streaming application
    Patent number: 10338989
    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.

  • Checkpointing a set of stream computing data
    Patent number: 10305958
    Abstract: Disclosed aspects relate to checkpointing a set of stream computing data with respect to a stream computing environment having a set of windowed stream operators including both a first windowed stream operator and a second windowed stream operator. It may be identified that the first windowed stream operator has a first subset of the set of stream computing data. It may be identified that the second windowed stream operator has the first subset of the set of stream computing data. It may be determined to checkpoint the first subset of the set of stream computing data without a redundant checkpoint related to the first and second windowed stream operators. The set of stream computing data may be checkpointed without the redundant checkpoint of the first subset of the set of stream computing data.
