根因分析
命令引用了一个在指定流键上尚未创建的消费者组。
English
A command referenced a consumer group that has not been created on the specified stream key.
官方文档
https://redis.io/docs/latest/develop/data-types/streams/解决方案
-
使用 XGROUP CREATE mystream mygroup $（或 0 表示所有消息）创建消费者组。例如：redis-cli XGROUP CREATE mystream mygroup $。
-
在使用 XREADGROUP 之前，使用 XINFO GROUPS mystream 验证组是否存在。
无效尝试
常见但无效的做法:
-
Recreate the stream key with the same name
60% 失败
Deletes all stream data and existing consumer groups; the group still won't exist unless explicitly created.
-
Use XINFO GROUPS mystream to list groups, but not create one
80% 失败
Only lists groups; does not resolve the missing group error.
