Current configuration on the wiki
0545fdc3af
Large wiki farms may have to purge servers concurrently (instead of one at a time) in order to keep up with new writes and delete expired rows faster than new rows are written. The parameter for this uses server tags for three reasons: * Maintenance risk and complexity. This requires the least information about MW configuration to be hardcoded in the scheduled maintenance cronjob (compared to: server indexes which are a runtime concept, or specific hostnames/IP/ tableprefixes which may change and should not require coordinating changes elsewhere). * Operational convenience. By using server tags, the parameters don't have to vary between data centers. * Code complexity. The current code for obtaining connections is based on server indexes, which are easy to mapped at runtime from server tags. Other ways of identifying shard like hostnames are either an awkward fit (as they don't uniquely identify a shard per-se, with multiple instances on the same hardware at WMF), or require SqlBagOStuff to store and maintain more information about connections than it currently has readily available.

MediaWiki is a free and open-source wiki software package written in PHP. It serves as the platform for Wikipedia and the other Wikimedia projects, used by hundreds of millions of people each month. MediaWiki is localised in over 350 languages and its reliability and robust feature set have earned it a large and vibrant community of third-party users and developers.
MediaWiki is:
- feature-rich and extensible, both on-wiki and with hundreds of extensions;
- scalable and suitable for both small and large sites;
- simple to install, working on most hardware/software combinations; and
- available in your language.
For system requirements, installation, and upgrade details, see the files RELEASE-NOTES, INSTALL, and UPGRADE.
