public void next() {
        this.enableNext.set(true);
        this.breakPointLock.release();
    }
Release the current lock and wait for the events arrive to the next point. For this to work, the next endpoint
is not required to be a checkpoint marked by the user.
For example, if user adds breakpoint only for the IN of query 1, next will track the event in OUT of query 1.
