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.

Abstract: Methods and apparatus, including computer program products, implementing and using techniques for data stream processing in a runtime data processing environment. A stream processing graph that includes several connected operators is received. Source code of the operators is analyzed to identify hints describing whether an operator contains data structures, method parameters or other data that can be applied in a parallelization data processing environment. Performance metrics of the data processing environment within parallel regions is evaluated to determine whether data processing resources can be dynamically scaled up or down. In response to determining that the data processing resources can be dynamically scaled up, one or more operators are split to be processed on two or more parallel processing resources. In response to determining that the data processing resources can be dynamically scaled down, one or more operators are combined to be processed on a single parallel processing resource.

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.

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.

Abstract: Techniques are described for re-starting queries based on an expected amount of data to be changed in a database. Embodiments of the present disclosure may generally receive a first query to be executed against a database, and start execution of the first query against the database according to a first access plan. Upon detecting, during execution of the first query, that an amount of data to be changed in one or more tables of the database as a result of a second query satisfies a predetermined condition, embodiments of the present disclosure determine whether to re-start execution of the first query against the database with a second access plan different from the first access plan or wait a predetermined period of time before re-starting execution of the first query against the database with the first access plan.

The content of the composed message may be modified based on the difference.

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.
