Hi
To create:
ColumnFamilyDefinition counters = createBasicCfDef(
KEYSPACE, Consts.COUNTERS, ComparatorType.UTF8TYPE,
null, "CounterColumnType", "CompositeType(UTF8Type,UUIDType)");
counters.setReplicateOnWrite(true);
cluster.addColumnFamily(counters, true);
to increment (add) counter
public static void incrementCounter(Composite key,
String columnName, long inc) {
Mutator<Composite> mutator =
HFactory.createMutator(keyspace,
CompositeSerializer.get());
mutator.incrementCounter(key,
Consts.COUNTERS, columnName, inc);
mutator.execute();
}
