It's difficult proposing alternatives without knowing all the requirements.<br><br>If there are no rules that require the presence of transactions with<br>unknown/indeterminate account numbers, a caching strategy might<br>
be considered. Clearly, this would render relying on Fusion features<br>obsolete, and (temporary) retractions would have to be done<br>explicitly. Most frequently used accounts would remain in WM up<br>for the period you have to consider. Others would drop out due to<br>
being idle for a certain period. A new transaction for some <br>swapped out account would trigger reloading of old transactions.<br>(This is akin to some page swapping strategy used to implement<br>virtual memory in operating systems.)<br>

Thank you very much for so qucik response. I cannot even believe it!<br>
<br>
As far as I know, the Fusion engine has to store the event details for<br>
sliding windows. Because if an event<br>
<br>
in the window is expired, the Fusion engine still need this event details<br>
to update the accumulate results.<br>
<br>
So, I think storing the accumulate results for per day could not conform to<br>
Fusion's logic.<br>

Thank you, all!<br>
