🐻‍❄️❄️ Snowflake

Easy to use Kotlin library to help you generate Twitter snowflakes asynchronously

v0.1-beta | 📜 Documentation

Snowflake is a Kotlin multiplatform library to help you generate Twitter snowflakes in a single node environment or in a clustered environment. This library was majorly inspired by @bwmarrin's Go Snowflake library.

Features

• Distributed snowflake to help you generate snowflakes on each node with the SnowflakeNodes API.
• kotlinx.serialization support to easily (de)serialize snowflakes.
• Simple and usable way to generate Twitter snowflakes
• Asynchronous support via Kotlin's coroutines

Usage

View the installation guide on how to install the library in your Kotlin project.

The formatting of the snowflake is relatively the same as the ID Format that Twitter uses.

// Defaults with node 0 and epoch of Twitter's snowflake
val snowflake = Snowflake()

val id = snowflake.generate()
// => returns [org.noelware.charted.snowflake.ID]

Benchmaking

Since generating snowflakes should be fast as possible, we provide a benchmark suite in the benchmarks folder with kotlinx.benchmark
