Like... I want to know how druid recover when connection to deepstorage having trouble

Speaking of ingestion I think it will fail to complete the ingestion task so won't commit the offsets on kafka. On the next ingestion run, the task will read the same data again, trying to put them in deepstorage in the end of the task. And goes on. iiuc ingestion tasks only succeed if they get persisted to the deepstorage. PS: Which (again iiuc) means that you may see those data in results if your query minds recent data and the broker asks the middlemanager but then disappear because the ingestion task failed. Take that with a grain of salt though. Still trying to get a deeper understanding of the failure semantics there.
