Examples with StateFactory storm.trident.state.StateFactory used on opensource projects

Example 1 with StateFactory

use of storm.trident.state.StateFactory in project jstorm by alibaba.

the class Stream method window.

private Stream window(WindowConfig windowConfig, WindowsStoreFactory windowStoreFactory, Fields inputFields, Aggregator aggregator, Fields functionFields, boolean storeTuplesInStore) {
    projectionValidation(inputFields);
    windowConfig.validate();
    Fields fields = addTriggerField(functionFields);
    // when storeTuplesInStore is false then the given windowStoreFactory is only used to store triggers and
    // that store is passed to WindowStateUpdater to remove them after committing the batch.
    Stream stream = _topology.addSourcedNode(this, new ProcessorNode(_topology.getUniqueStreamId(), _name, fields, fields, new WindowTridentProcessor(windowConfig, _topology.getUniqueWindowId(), windowStoreFactory, inputFields, aggregator, storeTuplesInStore)));
    Stream effectiveStream = stream.project(functionFields);
    // create StateUpdater with the given windowStoreFactory to remove triggered aggregation results form store
    // when they are successfully processed.
    StateFactory stateFactory = new WindowsStateFactory();
    StateUpdater stateUpdater = new WindowsStateUpdater(windowStoreFactory);
    stream.partitionPersist(stateFactory, new Fields(WindowTridentProcessor.TRIGGER_FIELD_NAME), stateUpdater, new Fields());
    return effectiveStream;
}
