Snowflake ID is a unique identifier commonly used in distributed systems to generate unique IDs with a timestamp component. It is designed to ensure uniqueness, even in distributed and highly concurrent environments.
npm install @skorotkiewicz/snowflake-id> Snowflake ID is a unique identifier commonly used in distributed systems to generate unique IDs with a timestamp component. It is designed to ensure uniqueness, even in distributed and highly concurrent environments.
The Snowflake ID typically consists of three components:
1. Timestamp: Representing the time when the ID was generated.
2. Machine ID: Identifying the machine or node that generated the ID.
3. Sequence Number: Ensuring uniqueness in cases of multiple IDs generated within the same millisecond.
By combining these components, Snowflake IDs provide a reliable way to generate globally unique identifiers, making them valuable for applications such as distributed databases, messaging systems, and more.
