name keys so they can be found, expired, and invalidated safely.

• Use namespaces with colons: shop:product:42:v1.
• Include a version in the key to change formats without clashes.
• Keep keys short but readable; large key sets cost memory.
• Never use KEYS * in production; it scans everything and blocks. Use SCAN with a match pattern.
• Group related keys (or use a version/tag key) so invalidation does not need scanning.
