On k8s, for example running multiple parallel jobs that need to initialize only once, It used to work for me the redis redlock (it's around with multiple implementations). The first job takes the lock while initializing, the rest just waits the release, to start working on prepared items by the first. On asyncio, caches, we used a lock to prevent dogpiling on cache initialization.. prevent multiple tasks cashing the same in parallel.
