Gitlab::ThreadMemoryCache.cache_backend
Add a memory cache local to the thread to reduce Redis load Loading `ApplicationSetting` from Redis was responsible for at least 50% of the CPU load of the Redis cluster on GitLab.com. Since these values generally don't change very much, we can load this from the database and cache it in memory, skipping Redis altogther. We use `ActiveSupport::Cache::MemoryStore` as a drop-in replacement for `RedisCacheStore` even though we probably don't need synchronized access within `Thread.current`.
