On the EventIterator interface I would like to change the method signature, from:

    boolean hasNext();

To:

    boolean hasNext() throws InterruptedException;

and remove this from the EventIterator interface:

 extends Iterator<Event>,

This is a possible breaking change. any comments?

Hi,

Lets say this is my event stream:

(User1, event1)
(User1, event2)
(User1, event1)
(User2, event2)

I want to check that any user that has event1 has also event2 (any user can have many such groups). Also, I don't want to specify a specific user, I want to check them all. I tried creating a sequence that matches this:

{
    "comment": "First tdl",
	
	
	
    "sequences": [{
        "type": "CONTAINER",
        "name": "BattleStarted has BattleEnded",
        "sequenceMaxTime": "PT3M",
        "checkPoints": [
        {
            "eventType": "1",
            "set": ["BS_userId=userId", "BS_battleId=p_battleId", "BS_timestamp=timestamp"]
        }, 
        {
            "eventType": "2",
            "match": "userId==BS_userId && p_battleId==BS_battleId",
            "validate": "timestamp > BS_timestamp"
        }]
    }]
}

The problem is checkpoint only matches first event it finds, so in this case, only first 2 events will be checked, failing to report that User1 does not have event2 for all event1. Is it possible for a sequence to search through all possible matches?
