Abstract: A real-time click system to process advertisement (ad) clicks includes a real-time listener operative to listen for, and store in a memory, a plurality of click event packets emitted by an ad server when corresponding ads are clicked by web users. A sequencer stores the click event packets in a database. A collector is coupled with the real-time listener and the sequencer and is operative to retrieve the plurality of click event packets, upon request, from the memory at a predetermined time interval. The collector also determines a partition number associated with each of the plurality of click event packets and sends to the sequencer the click event packets having a partition number corresponding to the sequencer.
