Class SInterCommand

Available since 1.0.0.

SINTER key [key ...]

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

SINTERSTORE destination key [key...]

This command is equal to SINTER, but instead of returning the resulting set, it is stored in destination.

If destination already exists, it is overwritten

For example:

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

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).

Return value

Array reply: list with members of the resulting set.
