A method (100; 300) for migrating an event detector of a first node ( N 1) of a distributed computing system to a second node (N 2) 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 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 ( N 1), the method (100; 300) comprising: transferring (112; 312), from the first node (N 1) to the second node ( N 2), information on event delays corresponding to the plurality of input events ( e; A, B, C) at the first node ( N 1); transferring (114; 314) the content of the event detector from the first node (N 1) to the second node ( N 2) 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 (N 1) to the second node ( N 2); receiving, at the second node ( N 2), the plurality of input events ( e; A, B, C) forwarded from the first node ( N 1) and, in parallel, from originating event detectors associated to the plurality of input events; and processing (124; 320), at the second node ( N 2), the plurality of received input events ( e; A, B, C) based on the transferred information on the event delays and based on event delays of the plurality of input events ( e; A, B, C) received from the associated originating event detectors, wherein processing (124; 320) the plurality of received input events ( e; A, B, C) at the second node ( N 2) comprises determining a time for relaying a received input event to the migrated event detector based on its event occurrence time and a maximum event delay (K' D) of the plurality of input events, wherein the maximum event delay value ( K' D) is based on the transferred information on the event delays and based on event delays of the plurality of input events ( e; A, B, C) received from the associated originating event detectors. transferring (112; 312), from the first node (N 1) to the second node ( N 2), information on event delays corresponding to the plurality of input events ( e; A, B, C) at the first node ( N 1); transferring (114; 314) the content of the event detector from the first node (N 1) to the second node ( N 2) 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 (N 1) to the second node ( N 2); receiving, at the second node ( N 2), the plurality of input events ( e; A, B, C) forwarded from the first node ( N 1) and, in parallel, from originating event detectors associated to the plurality of input events; and processing (124; 320), at the second node ( N 2), the plurality of received input events ( e; A, B, C) based on the transferred information on the event delays and based on event delays of the plurality of input events ( e; A, B, C) received from the associated originating event detectors, wherein processing (124; 320) the plurality of received input events ( e; A, B, C) at the second node ( N 2) comprises determining a time for relaying a received input event to the migrated event detector based on its event occurrence time and a maximum event delay (K' D) of the plurality of input events, wherein the maximum event delay value ( K' D) is based on the transferred information on the event delays and based on event delays of the plurality of input events ( e; A, B, C) received from the associated originating event detectors.
