rnewson commented on issue #1987: Best Practices for blue-green clusters in production (with external replication clients) URL: https://github.com/apache/couchdb/issues/1987#issuecomment-478268636 All nodes in the blue cluster should have the same UUID, All nodes in the green cluster should have the same UUID, but the blue UUID should not be the same as the green UUID. The ordering of documents in each cluster will not be the same, so you absolutely cannot make the same 'seq' value mean the same thing for both clusters. So, yes, you are doing something crazy. -- Robert Samuel Newson [email protected] On Fri, 29 Mar 2019, at 15:39, irishmark wrote: > It looks like the answer to this might be to perform a search and replace on the _local shard-sync documents on all the nodes when starting a new cluster on new hostnames.
