View Source Spawn.Cluster.StateHandoff (spawn v1.0.0-rc1)
This handles state handoff in a cluster.
It uses the DeltaCrdt library to handle a distributed state, which is an eventually consistent replicated data type. The module starts a GenServer that monitors nodes in the cluster, and when a new node comes up it sends a "set_neighbours" message to that node's GenServer process with its own DeltaCrdt process ID. This is done to ensure that changes in either node's state are reflected across both.
The module also handles other messages like "handoff" and "get" to put and retrieve data from the DeltaCrdt state, respectively.
