Geoevent, ObjectID, and Incremental Updates

Here's a fun one.

We are building an application that uses Geoevent to poll a map service for features (permits in this case), geotag the permits with a geofence, and write the output to a new feature class.

The problem we are having relates to the 'Get Incremental Updates' property and the way our permit data gets updated.

I really want to set the GEV Service to poll every 5-30 minutes (doesn't need to be 'real time') and only bring over new OR modified records. My understanding is that this is what 'get incremental updates' does (at least for new features).

The problem we have is that nothing gets picked up at all when we set 'Get Incremental Updates' to 'yes'. My concern is that because our permit data gets truncated/appended every night, the objectids get shuffled as part of that process, thereby rendering the Get Incremental Updates option powerless to do what it's designed to do.

Just wondering if that's the correct interpretation of this functionality.

Thanks -

Allen
