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.

Required arguments

slot

The hash slot to count the keys in.
