FAQ
Q: What happens if the key already exists?
A: By default, the existing value will be overwritten.
Q: Can I store complex objects in Redis?
A: Yes. JSON objects can be stored as strings, which can then be parsed back when retrieved.
Q: Do I need to set a TTL?
A: No. TTL is optional. Without it, the key will persist until explicitly deleted.
