詳細
This setting controls the cache used by methods that store temporary values that need to be seen in all datacenters.
This is not true of $wgMainCacheType , which should be a fast and local-only cache.
Ideally, a better effort should be made to reduce evictions are data loss during power outages that main cache stores (e.g. redis with disk-persistence enabled and allkeys-lru
).
Nevertheless, the store does not need to be a robust ACID compliant database, it should merely be a fast, memory-based, store that replicates data to all sites.
A modest amount of eviction or lost data (such as on fail-over) can be tolerated.
