Description

This chain element waits for REFRESH_REQUESTED event from the upstream and triggers refresh when received.

It also has "Local Notification" option to trigger refresh for different connections belonging to the same client.
Example:
Screenshot from 2022-07-14 14-59-55

To trigger conn1-3 to refresh the connection, we can use local notification

@glazychev-art Local notifier is an interesting idea... how do you see using it?

@edwarnicke
Common NSC will not use it - is enough to receive only upstream monitor events with REFRESH_REQUESTED state.
But for the vl3-client, we can also set an option WithLocalNotification():

...
upstreamrefresh.NewClient(ctx, upstreamrefresh.WithLocalNotifications()),
...

All outgoing requests are subscribed to events (created a new simple chan struct{}). And if one of the already created connections receives REFRESH_REQUESTED state from its upstream - it notifies others to also refresh their connections (to other vl3 endpoints). It calls notify function which sends a notification to each subscriber. For these subscribers, this will mean the same as REFRESH_REQUESTED.

@glazychev-art Ah yes... of course :) Makes total sense.
