SINTER

Syntax
SINTER key [key ...]
Available since:
1.0.0
Time complexity:
O(N*M) worst case where N is the cardinality of the smallest set and M is the number of sets.
ACL categories:
@read, @set, @slow,

Returns the members of the set resulting from the intersection of all the given sets.

For example:

key1 = {a,b,c,d}
key2 = {c}
key3 = {a,c,e}
SINTER key1 key2 key3 = {c}

Keys that do not exist are considered to be empty sets. With one of the keys being an empty set, the resulting set is also empty (since set intersection with an empty set always results in an empty set).

Examples

SADD key1 "a" SADD key1 "b" SADD key1 "c" SADD key2 "c" SADD key2 "d" SADD key2 "e" SINTER key1 key2
