Snowflake

Snowflake ID generator implementation in Crystal programming language, which is designed to generate unique, time-based identifiers using a 64-bit structure. These identifiers consist of a timestamp component, a machine or process ID, and a sequence number to ensure uniqueness within the same millisecond.

Installation

1. Add the dependency to your shard.yml:

   dependencies:
     snowflake:
       github: mamantoha/snowflake
   

2. Run shards install

Usage

require "snowflake"

machine_id = 1_u64 # Assign a unique machine/process ID
generator = Snowflake.new(machine_id)
snowflake_id = generator.generate_id
puts snowflake_id

# To convert a Snowflake ID back to a UTC timestamp
utc_time = Snowflake.id_to_utc(snowflake_id)
puts utc_time
