This is a basic DHT implementation using the Kademlia routing protocol. It's not an implementation of a full Kademlia node. You can find an example implementation of a Kademlia node here: https://github.com/cgrotz/kademlia-example
Simply include Kademlia as a dependency in your code:
<dependency>
<groupId>de.cgrotz</groupId>
<artifactId>kademlia</artifactId>
<version>1.0.1</version>
</dependency>// In production the nodeId should be static for an individual node
Kademlia kad = new Kademlia(new NodeId(), "127.0.0.1", 9000);
// Bootstrap using a remote server (there is no special configuration on the remote server necessary)
kad.bootstrap("127.0.0.1", 9001);
// Store a key/value pair in the DHT
kad.put("key", "value");
// Retrieve a key/value pair from the DHT
kad.get("key", value -> { ... });
// Or synchronously with
kad.get("key");See the Getting Started guide for more information. Protocol gives you information on the protocol.
- Extend Testing
- Bucket Refreshing
- Key Republishing
- Client retry behavior
- Caching
- Store value as continuous log of events?
- Provide TLS encryption with Key Exchange for inter node communication
- provide local Unix Domain Socket interface for IPC
- Switchable local storage implementation (e.g. to enable other storage engines like Levels DB)
