Question about deleted paths about gnmic HOT 4 OPEN

If I understand what you are trying to achieve correctly, I would say you don't really need delete events.
All you need is knowing that a certain row in your table does not exist anymore after a certain timestamp.
That way you can show the same table at different points (intervals?) in time highlighting the diffs.

Deletes are more for a system that ingests events and reacts to a change (e.g: trigger an alarm)
Keep in mind that gNMI sample subscriptions do not include delete notifications.

Postgres will be config heavy, you need to create a schema and explicitly map each received path to a key/field.

I think I forgot to add one detail. In my solution data collection is based on stream mode on-change rather than sample. So we don't get full table data every interval. Those tables in network devices are changing relativety rarely. It doesn't make sense to subscribe interval based.

So in order to tell rows in the table at given point in time, I need to:

1. Take latest entries of each row within time range starting from when the subsribtion has started (or restarted) as every time it starts full table is sent. (Or maybe I use heartbeat-interval of 1h to make it easier)
2. Remove rows where last event was delete

Or is there way to solve the issue without delete events?

I see your point, an additional tag that says delete=true can be added when a delete is received.
