Globals should only be used for data that is constant over the life of the working memory, which is not so in your case.

Maybe you should just use a fact counter. If you don't want to affect your code you could insert it in a separate rule.

Hello,
I would like to take 100 sampling facts for rule and persist it in the db
and ignore other data.
How Can I maintain the counter? as global variable? Please clarify with
sample code.
I tried following way and but it does not work as expected.

Ex:
global Integer counter;
rule "get sampling data"
  when fact : Foo(some condition) && eval(counter <= 100)
  then
   counter++
  // do some condition
end
