Is there any upper limit on the number of members a sorted set in redis can store?
For example, according to this link, 2^32 - 1 different members can only be stored in redis set, list. No such upper limit is mentioned for redis sorted set. So should I assume that, the upper limit depends on the memory that is available or there is a fixed number?
The same limit - 2^32-1 - applies to Redis' Sets and Sorted Sets as well.
An excerpt from the Data types page at redis.io:
While not mentioned in that page, both Sets and Sorted Sets use the same underlying data structure (which, in turn, is a hash). Hence, they share the same limit.
