Aggregation/Correlation sessions can be viewed through the Aggregation Session Inspection GUI. The sessions can be searched for and released for further down-stream systems for further processing.
Aggregation Flush Functionality
The APL function aggregationHintFlushSessions is available in Analysis and Aggregation APL code in Batch Workflows. It is used to indicate that the timeout function block, in the APL code for the specified Aggregation Agent, will be executed for all the sessions in the storage that have a timeout value. The timeout block execution will be performed after the drain function block has been executed in the specified Aggregation Agent. This can be useful before system upgrades or maintenance windows where it is desirable to keep temporary data at a minimum.
Couchbase Aggregation
Couchbase can be used to store aggregation session data in real-time workflows. By selecting a mirror profile you may also acquire read only access to sessions in a secondary Couchbase cluster. This is useful in various failover scenarios. The mirror session data can be extracted via APL code. Storing aggregation sessions in Couchbase improves scalability and enables sharing of data across workflows and geographic locations.
