Flake4J - Flake ID generator for Java

This is an implementation of the Flake decentralized, k-ordered ID generation algorithm by Boundary.

There is no server implementation yet. To avoid non-unique IDs, it is the programmer's responsibility to ensure that only one instance of the ID generator is active in a single node (if the MAC address based node identification is used).

This implementation generates 128-bit IDs.

Usage

Artifacts are available on Maven Central.

Gradle:

compile group: 'com.github.charithe', name: 'flake4j', version: '1.0.2'
// Create an ID generator that uses the machine's MAC address for node identification
Flake4J f4j = Flake4J.newInstance();

// Use a custom node identifier instead of the MAC address
NodeIdentifier nodeIdentifier = () -> uniqueNodeIdentifier // long value
Flake4J f4j = Flake4J.newInstance(nodeIdentifier);
