                                       Class<K> k,
                                       Class<V> v)

Method Detail

pfadd

@SafeVarargs
public final io.smallrye.mutiny.Uni<Boolean> pfadd(K key,
                                                   V... values)

Description copied from interface: ReactiveHyperLogLogCommands

Execute the command PFADD. Summary: Adds the specified elements to the specified HyperLogLog. Group: hyperloglog Requires Redis 2.8.9

Specified by:

pfadd in interface ReactiveHyperLogLogCommands<K,V>

Parameters:

key - the key

values - the values

Returns:

true at least 1 HyperLogLog internal register was altered. 0 otherwise.

pfmerge

@SafeVarargs
public final io.smallrye.mutiny.Uni<Void> pfmerge(K destination,
                                                  K... sources)

Description copied from interface: ReactiveHyperLogLogCommands

Execute the command PFMERGE. Summary: Merge N different HyperLogLogs into a single one. Group: hyperloglog Requires Redis 2.8.9

Specified by:

pfmerge in interface ReactiveHyperLogLogCommands<K,V>

Parameters:

destination - the key

sources - the source keys

Returns:

a Uni emitting a null item on completion

pfcount

@SafeVarargs
public final io.smallrye.mutiny.Uni<Long> pfcount(K... keys)

Description copied from interface: ReactiveHyperLogLogCommands

Execute the command PFCOUNT. Summary: Return the approximated cardinality of the set(s) observed by the HyperLogLog at key(s). Group: hyperloglog Requires Redis 2.8.9

Specified by:

pfcount in interface ReactiveHyperLogLogCommands<K,V>

Returns:

The approximated number of unique elements observed via PFADD.
