根因分析

流被修剪或删除，导致消费者组的 last-delivered-id 早于流中最旧的条目，导致状态不一致。

English

The stream was trimmed or deleted, causing the consumer group's last-delivered-id to be older than the oldest entry in the stream, leading to an inconsistent state.

解决方案

  1. 运行 'XGROUP SETID mystream mygroup 0-0' 重置到开头，然后使用 XREADGROUP 从最旧条目重新处理。
  2. 设置 XTRIM 的最小 ID 早于组的 last-delivered-id：'XTRIM mystream MINID ~ <last-delivered-id>'。
