Azure Managed Redis: cache-aside pattern, TTL and invalidation, eviction policies

Redis is an in-memory data store that answers in well under a millisecond, which makes it the standard cache in front of slower databases and expensive AI model calls. Azure Managed Redis is Microsoft's current managed Redis offering, built on Redis Enterprise software, with tiers optimized for memory, balance or compute, clustering, high availability and optional modules such as search and JSON. From Python you connect with the redis (redis-py) package over TLS, authenticating with an access key or, preferably, Microsoft Entra ID.
