 	PTTL(key string) (Result[int64], error)
+
+	// Unlink (delete) multiple keys from the database. A key is ignored if it does not exist.
+	// This command, similar to Del However, this command does not block the server
+	//
+	// Note:
+	//	 In cluster mode, if keys in keys map to different hash slots, the command
+	//   will be split across these slots and executed separately for each. This means the command
+	//   is atomic only at the slot level. If one or more slot-specific requests fail, the entire
+	//   call will return the first encountered error, even though some requests may have succeeded
+	//   while others did not. If this behavior impacts your application logic, consider splitting
+	//   the request into sub-requests per slot to ensure atomicity.
+	//
+	// Parameters:
+	//  keys - One or more keys to unlink.
+	//
+	// Return value:
+	//  Return the number of keys that were unlinked.
+	//
+	// Example:
+	//	result, err := client.Unlink([]string{"key1", "key2", "key3"})
+	//	if err != nil {
+	//	    // handle error
+	//	}
+	//	fmt.Println(result.Value()) // Output: 3

+	// Type returns the string representation of the type of the value stored at key.
+	// The different types that can be returned are: string, list, set, zset, hash and stream.

+	// Parameters:
+	//  key - string
+	//
+	// Return value:
+	//  If the key exists, the type of the stored value is returned. Otherwise, a none" string is returned.
