Change Details

For a deployment of the upcoming wikidata query service we'll need some hardware: - We should be able to share the cassandra cluster with restbase (at least initially) - We need at least two titan nodes (for redundancy), with load balancing / fail-over with LVS. These are mainly CPU & memory bound. We currently use einsteinium as a test host, which is relatively close to the desired hw specs for Titan. Regarding the timeline: This project is still at a relatively early point in its development, but it would be good to get the hardware ready in time so that it does not become hectic / a blocker.

For a deployment of the upcoming wikidata query service we'll need some hardware. Initially, we probably need one work machine and one spare for disaster recovery (full recovery loading from dump takes several days, so unless we want to live the life of danger, we'd need a hot spare). Exact specs TBD soon.
