Abstract
Embodiments relate to a concept for migrating an event detector of a first node (N1) of a distributed computing system (200) to a second node (N2) of the distributed computing system, wherein the event detector processes a plurality of input events (e; A, B, C) to generate at least one output event (D) based on the input events, wherein each of the input events has associated therewith an individual event delay corresponding to a propagation time of the input event to the first node (N1). It comprises transferring (112; 312), from the first node (N1) to the second node (N2), information on event delays corresponding to the plurality of input events (e; A, B, C) at the first node (N1); transferring (114; 314) a content of the event detector from the first node (N1) to the second node (N2) to obtain a migrated event detector at the second node; forwarding (116; 316) the plurality of input events (e; A, B, C) from the first node (N1) to the second node (N2); receiving (122), at the second node (N2), the plurality of input events (e; A, B, C) forwarded from the first node (N1) and, in parallel, from originating event detectors associated to the plurality of input events; and processing…
