Hi, it is a breaking change indeed. About the plugin detail, I have explained in the main thread.
> Snowflake depends on a unique worker_id, which is acquired from etcd. If etcd fails, each request with request-id plugin that uses the snowflake algorithm needs to try to retrieve a unique worker_id. This has a significant impact on performance.
