Finding values by using partial key name in a Redis Sorted Set

Question

I have a sorted set which has the following key name and values :

zrange bargraph:branch:1:category:2:product:4
1) \"76\"
2) \"55\"
3) \"10\"
4) \"84\"
<         


        

Answer 1

As you've mentioned, KEYS is inefficient because the engine performs a linear scan for keys. Unfortunately, there is no wildcard solution such as you are looking for

Consider using a SET for your product keys per category:

SADD bargraph:branch:1:category:2 1 2 3 4

to fetch all set category members do:

SMEMBERS bargraph:branch:1:category:2

If you don't care about summing your scores, or have different items per a sorted set, you can do a union of your per product sorted sets like this:

ZUNIONSTORE bargraph:branch:1:category:2:product:all 4 bargraph:branch:1:category:2:product1 bargraph:branch:1:category:2:product2 bargraph:branch:1:category:2:product3 bargraph:branch:1:category:2:product4

and now you can zrange bargraph:branch:1:category:2:product:all

You pipeline the above operations for better performance
