Network events occurring in the specific network environment can be identified. The network events can be aggregated to form an aggregated network event using the event correlation rules maintained based on the characteristics of previously occurring network events. The aggregated network event can subsequently be presented to a user.

Abstract: Software for a distributed streaming platform receives a specification for a streaming application and converts the specification into a logical plan that includes a directed acyclic graph (DAG) with operators as nodes and streams as edges. The software translates the logical plan into a physical plan using any stream modes as specified and with one or more instances of the operators per any static partitioning. Then the software obtains a plurality of containers running on a networked cluster of servers. One slave executes in each container. The software assigns the instances to the slaves for execution according to an execution plan that depends at least in part on the physical plan and number of containers obtained. Each slave monitors throughput of the streaming windows through the instances in the container and other statistics related to service level and reports the results of the monitoring, which are used for dynamic adjustment.

Abstract: Software receives a data stream for an application running on a distributed streaming platform over a networked cluster of servers. The software converts the data into a plurality of data tuples structured according to a schema. The software repeatedly emits a plurality of the data tuples as a streaming window, which is separated from other streaming windows by a leading control tuple associated with an ordinal identifier for the streaming window. The streaming window is a sequential sequence of tuples that is associated with a recovery policy. Then the software emits a checkpointing tuple after a plurality of streaming windows. The checkpointing tuple causes checkpointing of an instance of an operator for the application when the checkpointing tuple is received by the instance. Each of the operations is executed by one or more processors in real time or near real time rather than offline.

Abstract: Software for a distributed streaming platform receives an application. The application is structured as a directed acyclic graph (DAG) with instances of operators as nodes and streams as edges between nodes. Multiple instances of an operator access a shared database. The software receives a pre-defined hint associated with the application. The pre-defined hint sets a maximum period of time for local caching of a result from a query of the database by each of the multiple instances. The software launches the application by assigning the instances of operators to one or more containers provided by the streaming platform and initiating the streams. Each container is associated with a local cache. The software then receives a request from the application to make a dynamic adjustment that increases the maximum period of time for local caching of a result from a query of the database by each of the multiple instances.
