Manual:$wgChronologyProtectorStash

Details
The object store type of the ChronologyProtector position store.

This should be a fast storage system optimized for lightweight ephemeral data. The dataset access scope should include all application servers in the local datacenter. A set of single-key operations should maintain "best effort" linearizability (e.g. they observe linearizability unless connectivity/latency/disk problems arise).

Valid options are the keys of $wgObjectCaches, e.g. CACHE_* constants.
