I agree with you. So this tool only handle colocate meta, not all Doris meta. If the colocate meta is broken, the Fe could run normally. > > > And also, we currently don't have a framework to redirect the request from non-master FE to Master FE(which SQL has), so you need to send the request directly to the Master FE, which may not be able to do so in some environment, such as visiting a proxy with 3 Frontends under it. You need also think about it. > > This tool is for Doris Admin. So I think a Doris Admin should know which FE is master. Doris can redirect HTTP request to master, you can refer to "http/rest/MultiStart.java", call `redirectToMaster` can redirect request to the master.
