Description
This PR adds Leaderboard functionality, similar to Redis Leaderboard Overview.
The leaderboard is implemented using a Sorted Set backed by a SkipList implementation.
Instead of storing the actual strings for keys, we store pointers to these keys. Similarly for the values, we only store pointers to the actual values stored in the
store
. This allows us to keep the data structure space efficient.We also need to make sure that the KV pairs stored in the ZSet do not collide with the KV pairs in the general store.
