This is a feature of redis-enterprise only. (supported data type: SET, ZSET, HASH)

Start by reviewing the existing SET, ZSET, and HASH command implementations and their TTL-related entry points; the issue names no specific files or tests. Done means member-level expiration and TTL behavior matches the examples for all three supported data types, including removal after expiry.
