kademlia netty

Status: [ready to use]. [active maintainance]. Playground (sample runnable project) available here.

---

Implementation of kademlia API DHT using:

• Netty (as HTTP/1.1 server for each node, including ConnectionInfo with host and port)
• OKHttp (as RequestSender implementation)
• (Kademlia Gson Serialization)

This library uses BigInteger as Node IDs and NettyConnectionInfo as implementation of ConnectionInfo interafce.

However, it is still abstract, therefore you should implement some parts that are mentioned in kademlia API such as:

• DHT Repository
• Mechanism to persist and reload Routing Table
• You still need to configure NodeSettings. Default one may not be suitable for you.
• You need to implement KeyHasGenerator. This is used for bounding the key sizes to network size before storing messages.

Examples

There are few working examples in tests directory.

Main example has everything for you to start understanding how this library works. It creates 2 nodes and stores data in DHT.

Custom DTO Example is on top of previous example, but this time we are serializing and storing a different DTO object called Person instead of a simple String.
