Interface WorkerIdAssigner

All Known Implementing Classes:

FixedWorkerIdAssigner, IpBasedAssigner, MacBasedAssigner, RandomAssigner

public interface WorkerIdAssigner

Worker ID Assigner Interface 工作节点ID分配器接口

Provides automatic assignment of worker ID and datacenter ID for Snowflake generator. This is especially useful in containerized or Kubernetes environments.

为雪花ID生成器提供工作节点ID和数据中心ID的自动分配。 这在容器化或Kubernetes环境中特别有用。

Built-in Implementations | 内置实现:

• IpBasedAssigner - Based on IP address | 基于IP地址
• MacBasedAssigner - Based on MAC address | 基于MAC地址
• RandomAssigner - Random assignment | 随机分配

Usage Examples | 使用示例:

SnowflakeGenerator gen = new SnowflakeBuilder()
    .workerIdAssigner(IpBasedAssigner.create())
    .build();

Features | 主要功能:

• Strategy interface for assigning Snowflake worker IDs - 分配Snowflake工作ID的策略接口
• Pluggable worker identification mechanism - 可插拔的工作节点标识机制

Security | 安全性:

• Thread-safe: Implementation-dependent - 线程安全: 取决于实现
• Null-safe: No - 空值安全: 否

Since:

JDK 25, opencode-base-id V1.1.0
