Architecture

Auto Discovery

A node periodically executes 2 tasks responsible for auto discovers:

send discovery: send UDP packet on broadcast address to discover nodes
listen for discovery: receive UDP packets and send response back to the node who initiated discovery

Discovered nodes are added to the so cluster memberlist.
Another periodic task will then call the /api/node/status endpoint over HTTP on each node in the memberlist to get detailed informations about the node (e.g. freeHeap, available API endpoints).
