Hi Siddhi team, Do we have anyway of tracking what events are removed from any type of windows, length(batch), or time(batch)? I investigated that removeEvents may not be the right solution.
We have one requirement of migrating policy from one machine to another machine but keeping internal state there. Eagle uses policy in storm infrastructure, but one machine which holds the policy fails, then already-populated events in the window also are gone. Sometimes it is bad especially when we have built up a long window like monthly data. One possible way is to keep all events in the siddhi window to be snapshotted into application domain. Another way is to keep tracking what events are coming in and out, so application can track what are left in siddhi window. Here is the ticket for Eagle https://issues.apache.org/jira/browse/EAGLE-39 Do you have similar request before? Or what do you suggest? Thanks Edward Zhang
