Don't you fret because this isn't available. It's not difficult to collect facts over a variable interval, provided the timestamp is a regular property. An auxiliary fact defines the window's boundaries, and then you use ops like <= to select the facts.<div>

I'm evaluating the use of Drools Fusion for a new project and have a question about sliding windows that wasn't clear from the documentation. Does the time specification in a sliding window need to be hardcoded in the rule, or can it be derived from something else? Basically, I'm wondering whether I can write a rule that looks something like<br>
<br>
when<br>
...<br>
Window ($win : length)<br>
Number (intValue > $someValue) from accumulate (<br>
Sample($len: length, value > $someThreashold) over window:time ($win),<br>
sum($len) )<br>
then<br>
...<br>
end<br>
<br>
I know window:time() supports constant values like "10m", but can the window be driven from one of the other facts in the LHS picked up by the LHS of the rule?<br>
