[Wikidata-bugs] [Maniphest] [Commented On] T86561: Wikidata Query Service hardware
Joe added a comment. wdqs1001 installed just fine (after I figured out I needed at least one deploy for trebuchet to work). Installing wdqs1002 now, then I'll set up the LVS config.

Joe added a comment. Both servers are up and running and the wdqs-blazegraph service is running and the banner page shows on port 80. I will finish this work (adding LVS and eventually varnish support). Stas and James can now log into the machine and play with it - it's still not exposed to the public internet TASK DETAIL https://phabricator.wikimedia.org/T86561 EMAIL PREFERENCES https://phabricator.wikimedia.org/settings/panel/emailpreferences/ To: Joe Cc: gerritbot, RobH, Matanya, faidon, mark, JanZerebecki, Aklapper, Joe, Smalyshev, Manybubbles, jkroll, Wikidata-bugs, Jdouglas, aude, fgiunchedi, Dzahn, chasemp, Malyacko, Krenair, P.Copp ___ Wikidata-bugs mailing list Wikidata-bugs@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikidata-bugs

Joe added a comment. Yes, I was waiting for this evening's WQS meeting before reassessing priority/status, but marking it stalled is fair.

mark added a subscriber: mark. mark added a comment. Different rows for availability is one thing. We need to think about how to distribute the service to two different data centers as well, and should build this out in both from the start. Latency certainly //is// a significant factor there.

GWicke added a comment. In https://phabricator.wikimedia.org/T86561#971491, @JanZerebecki wrote: Do we want to have the Cassandra and Titan nodes be in the same rack as I assume that query performance is very latency sensitive? I don't think that there is a huge enough difference in latency between rows that would make it worth compromising availability. Cassandra nodes are spread out across racks (rows in our case) in order to improve availability by avoiding correlated failures that affect a single row. We should do the same for the Titan nodes.
