The library supervises a topology process that continually discovers peers and joins or prunes nodes as they become available or disappear. Its design embraces OTP principles: strategies implement a behavior, can be composed, and run under supervision for resilience. libcluster also emits events on nodeup/nodedown, allowing applications to react (for example, rebalance work or update registries) when membership changes. ...
