Abstract
When processing events associated with a group comprising multiple different sub-groups, a hash function can be applied to the sub-group identifier to map the events associated with the sub-group to different computational elements used to process the group's events. The hash value can be a number between 1 and n or 0 and n−1 where n is the number of computational elements available to the group. Data concerning the last time a particular value for a property was encountered in an event stream can be retained. On each computational element assigned to the group, the detection of a particular property value in an event of a sub-group can be collected, periodically aggregated and sent to each of the computational elements used by the group, thereby enabling the first detection of a new property value within a group of events to be determined.
