Topic on Talk:PoolCounter

I noticed that most of WMF's PoolCounter clients are set up to use a single server, and we were recommended to configure our client to use a primary server, then fallback to a secondary server if needed. This contradicts the documentation here for the servers variable, which mentions consistent hashing.

What is the preferred client implementation, primary with a fallback or consistent hashing across the two servers?

In https://noc.wikimedia.org/conf/highlight.php?file=ProductionServices.php I see that MediaWiki is configured to use two servers, using the consistent hashing system. Reading through PoolCounter_ConnectionManager it looks like if it can't connect to the server it intended, it'll fallback to the other one. So I guess the answer is both?

Great, thanks for looking! I never should have doubted the documentation ;-)
