示例1: persistentAggregate
import storm.trident.operation.impl.CombinerAggStateUpdater; //导入依赖的package包/类
public TridentState persistentAggregate(StateSpec spec, Fields inputFields, CombinerAggregator agg, Fields functionFields) {
projectionValidation(inputFields);
// replaces normal aggregation here with a global grouping because it needs to be consistent across batches
return new ChainedAggregatorDeclarer(this, new GlobalAggScheme())
.aggregate(inputFields, agg, functionFields)
.chainEnd()
.partitionPersist(spec, functionFields, new CombinerAggStateUpdater(agg), functionFields);
}
