Implement atomic access compatible with key transfers #8

Closed zllovesuki closed 2 years ago

zllovesuki commented 2 years ago

in concurrent kv operations while nodes are joining and leaving, it is possible that keys are transferred, but the network does not know about the new/old node yet. therefore, a concurrent kv could still be serviced by the old successor, causing lookup to fail.

possible solution: https://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.71.6111&rep=rep1&type=pdf

this must be resolved before we can put certmagic.Storage on DHT

2030fedea419590fc1b2611176f1cd73fdc83f3a partially unblocks this issue by providing key consistency during join/leave + concurrent kv operations

supposedly implemented in c31106400fcf812b1423d0ee862c7b9ccaec55de, however more testing is required
