Returns the number of keys in the specified Redis Cluster hash slot. The
command only queries the local data set, so contacting a node
that is not serving the specified hash slot will always result in a count of
zero being returned.

{{< note>}}During atomic slot migration operations (available since Redis 8.4.0), keys being imported or trimmed will be filtered out from the results.
