== Configuring Redis Cache in {product}
=== useRedisSets
The `useRedisSets` option lets you decide whether to use Redis sets for key management. By default, this option is set to `true`.

When `useRedisSets` is enabled (`true`):

* A namespace for the Redis sets is created, and all generated keys are added to that namespace, enabling group management of the keys.

* When a key is deleted, it's removed from the main storage and the Redis set.

* When using the clear function to delete all keys, every key in the Redis set is checked for deletion, and the set itself is also removed.

[NOTE]
In high-performance scenarios, enabling `useRedisSets` can result in memory leaks. If you are running a high-performance application or service, you must set `useRedisSets` to `false`.

When you set `useRedisSets` to `false`, the keys are handled individually and Redis sets are not utilized. This configuration might lead to performance issues in production when using the `clear` function, as it requires iterating over all keys for deletion.
