Abstract:
1. A computerized method for identifying from a real time event stream a transaction including events having latency, said computerized method comprising: receiving events from the real time event stream, wherein the events define a plurality of transactions to be identified, wherein each of the plurality of transactions includes a first event and a second event, said first event having a first latency relative to the real time event stream and said second event having a second latency relative to the real time event stream, said first latency and said second latency being configured by a user, wherein the first latency and the second latency are guaranteed as a function of at least one of the following: a different batch size in receiving the events from the real time event stream, increasing a frequency of processing event quanta from the real time event stream, and decreasing the frequency of processing event quanta from the real time event stream; identifying the first event from the received real time event stream; recording a time when the first event is received; determining a time period during which the second event will occur as a function of the first latency, the recorded time of the first event, and the second latency; and identifying the transaction having the first event and the second event based on the determined time period of the second event.
