consistent hashing vs. primary-secondary server nodes

Adamw (talkcontribs)

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?

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

Is it possible to limit CirrusSearch with redis instead of the C poolcounterd?

The server side poolcounterd software were extremely poor documented. It can be build by dpkg-buildpackage under some version of Debian, but mostly not.

Is it possible to limit CirrusSearch by redis instead of the C poolcounterd?

It should, this extension apparently doesn't provide anything more than using pool counter with the C poolcounterd daemon instead of the redis one.

Does the poolcounter server exist in Wikipedia-APT?

Sorry, didn't see this until now. What do you mean by "Wikipedia-APT"?

Summary by Legoktm

Documentation updated

Zoglun (talkcontribs)

Somebody truncate the PoolCounter.php file into empty, and failed to update the extension description page. (which I got it updated.)

It's now load through wfLoadExtension( 'PoolCounter' );

You will get PoolCounter_Client class not exist error if you stick with the old require_once method.

Thank you for updating the documentation!
