EventgetCoalescedEvents

EventgetCoalescedEvents is a function described in some event-processing systems for retrieving the current set of coalesced events. Coalescing is the practice of merging multiple occurrences of the same event type that occur in quick succession into a single representative event. The function serves to expose the reduced set of events that downstream handlers should process, helping to lower processing load in high-frequency scenarios.

In typical usage, eventgetCoalescedEvents may accept an options argument that can specify parameters such as a time window, a maximum number of events to return, or whether to include a count of merged occurrences. The function returns an array of coalescedEvent objects. Each coalescedEvent usually includes fields such as type, timestamp (representing when the coalesced event was produced), payload (a summarized or representative payload), and count (the number of original events merged into this coalesced event).

Semantics and behavior can vary by implementation. In general, the function is non-blocking and reflects the current state of the coalescing queue. Calling it may advance internal pointers or clear a portion of the queue, depending on design choices. The main goal is to provide a controlled view of events that minimizes duplication while preserving essential information about what occurred.

Limitations include potential loss of granularity, since precise timings of individual events are not preserved in coalesced form. Users should balance responsiveness with the need for detail. Related concepts include event debouncing, event throttling, and event batching.
