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.
