sendWakeUpNotification property
Whether sendEnvelope also fires a best-effort wake-up notification
(default on) after the put. Clients that run sync receive envelopes via
sync without it; sync-less clients rely on it (their startListening
monitors for it and does a remote sweep). It is best-effort: the
envelope is already durably stored, so a failed wake-up never fails the
send. A future atServer enhancement will emit this notification itself
on a put to an __ssenv key, at which point senders can leave it off.
Implementation
bool sendWakeUpNotification = true;
