Redis Caching Best Practices

Notes on keys naming conventions and eviction strategies when using Redis as a distributed cache.

1. Key Naming

Always use namespaces separated by colons: app:domain:object:id

Example: blog:posts:detail:getting-started

2. Setting TTL (Time To Live)

Never store cache entries without a TTL unless explicitly required. Always specify expiration times:

var options = new DistributedCacheEntryOptions()
    .SetAbsoluteExpiration(TimeSpan.FromMinutes(60))
    .SetSlidingExpiration(TimeSpan.FromMinutes(10));
