InvocableMap.StreamingAggregator
Be default, characteristics are a combination of InvocableMap.StreamingAggregator.PARALLEL
and InvocableMap.StreamingAggregator.RETAINS_ENTRIES, which is sub-optimal and should be
overridden by the aggregator implementation if the aggregator does not
need to retain entries (which is often the case).
InvocableMap.StreamingAggregator.PARALLEL,
InvocableMap.StreamingAggregator.SERIAL,
InvocableMap.StreamingAggregator.BY_MEMBER,
InvocableMap.StreamingAggregator.BY_PARTITION,
InvocableMap.StreamingAggregator.RETAINS_ENTRIES,
InvocableMap.StreamingAggregator.PRESENT_ONLYprotected void process(Object o, boolean fFinal)
If the fFinal parameter is true, the given object is a partial
result (returned by an individual parallel aggregator) that should be
incorporated into the final result; otherwise, the object is a value
extracted from an InvocableMap.Entry.
