Multiple copies in the object storage are stored only for a short period, because after they're uploaded by ingesters the compactor will deduplicate them, deleting source blocks and uploading compacted...

Ok, now I understand what you mean. The blocks upload from all ingesters (which happens nearly at the same time) may saturate the network, affecting read performances. Makes sense. What...
