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
when
...
Window ($win : length)
Number (intValue > $someValue) from accumulate (
Sample($len: length, value > $someThreashold) over
window:time ($win),
sum($len) )
then
...
end
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?
