I'm new to MediaWiki and currently exploring caching strategies to improve the performance of my wiki setup. Specifically, I have a scenario where MediaWiki is deployed in Kubernetes with multiple replicas running simultaneously.
I would appreciate any insights or best practices for managing caching in this environment, especially when it comes to the localisation (L10N) cache.
I have a few specific questions:
Apart from upgrades and extension changes, are there any other scenarios where the localisation cache changes? Is it possible for multiple MediaWiki instances (with the same codebase) to share a common L10N cache? What are the recommended strategies for handling caching in a multiple replica setup?
Thank you in advance for your help!
