storing set as a value for hash in redis

Question

I have file consisting of thousands of lines(each containing 3 fields, first is ak length string, then a number, third another string) of form:-

k|1|r1
k|1|r2
k|2|r2
k1|1|r3

I load it using redis-py, by using:-

sadd('k:1', 'r1')
sadd('k:1', 'r2')
sadd('k:2', 'r2')
sadd('k1:1', 'r3')

to form a mapping like

{
     "k:1"  : ("r1", "r2"),
     "k:2"  : ("r2"),
     "k1:1" : ("r3")
}

I intend to store the values of the form, by removing the repetitive information of k(which is ak length string common for the first 3 records):

{
     "k": {
         "1"  : ("r1", "r2"),
        "2"  : ("r2")
      }
     "k1": {
       "1" : ("r3")
     }
}

I have the idea of storing the value of storing the set under a different key, which can act as value for k in the hash. Is there a better way than that?

将集合存储在另一个键下将起作用，但是，如果集合是静态的，则不需要集合功能-相反，您可以保存自己的查找并将集合直接存储在地图中，例如，以逗号分隔的值（或如果您只有几个值，则使用任何适合的分隔符）；如果您有很多值，则使用逗号分隔的逗号分隔值（根据我的经验，如果字符串足够大，则g的成本（un）zip被降低的网络成本所抵消）。
