I've been working on a change to Synapse[1] to allow it to use the "set server addr" directive to reserve a large(ish) pool of servers in a backend and dynamically set server host/ports into that pool as they come and go, which would significantly reduce the number of restarts we have to do during code deployments. While implementing this I came across a problem where I can't figure out how to dynamically update the server name (server->id internally), which is important because the only host/port information on the stats page is the name afaik. The stats page is frequently used in my org to debug which servers are up or down so having nice names that say where a server is (basically the address) would be useful. Also, historically Synapse and other tooling has used the server name to figure out which hosts and ports already have server lines but I can work around this by using "show stats" and actually using the addr field instead of the name field. But, having a nice human readable name is still good I think.
Towards this end I've written up a patch (mostly just cribbed from set server fqdn) that updates the name for a server that enables: set server <b>/<s> name <name> Would that patch be generally useful or is there a better way to update the server name? Or maybe this is already possible and I just don't know how? I'm happy to make any needed changes. Thanks! -Joey Lynch [1] https://github.com/airbnb/synapse
