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.
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
I tried following way and but it does not work as expected.
global Integer counter;
rule "get sampling data"
when fact : Foo(some condition) && eval(counter <= 100)
// do some condition
