idgen（distributed unique ID generator）

Distributed unique ID generation using Redis as the coordination backend, suitable for high-concurrency scenarios.

The idgen module provides distributed unique ID generation using Redis as the coordination backend, suitable for high-concurrency scenarios.

Features

  • Distributed unique ID generation
  • Redis-based coordination
  • Batch ID generation support
  • Time-based ID structure
  • Collision avoidance mechanisms

31    fmt.Printf("Generated ID: %d\n", id)
32    
33    // Generate multiple IDs (batch)
34    ids, err := generator.GenMultiIDs(ctx, 10)
35    if err != nil {
36        panic(err)
