RedissonKeys.countExists(String... name) can help you to determine if the key exists, without knowing the type of it beforehand.

I think this what you need.

so i'll have to get all the keys before making this call? – priyankatanvani Jun 22 '17 at 15:28
You can check them one by one, if you like, by just using one key and check if the return value is 1. – Redisson_RuiGu Jun 22 '17 at 18:20

You can use isExists function to check whether the key is present in redis or not.
