Example 1 with SumLong

use of org.apache.apex.malhar.lib.window.accumulation.SumLong in project apex-malhar by apache.

the class ApexWindowedStreamImpl method countByKey.

@Override
public <K, STREAM extends WindowedStream<Tuple.WindowedTuple<KeyValPair<K, Long>>>> STREAM countByKey(Function.ToKeyValue<T, K, Long> convertToKeyValue, Option... opts) {
    WindowedStream<Tuple<KeyValPair<K, Long>>> kvstream = map(convertToKeyValue);
    KeyedWindowedOperatorImpl<K, Long, MutableLong, Long> keyedWindowedOperator = createKeyedWindowedOperator(new SumLong());
    return kvstream.addOperator(keyedWindowedOperator, keyedWindowedOperator.input, keyedWindowedOperator.output, opts);
}

Example 2 with SumLong

use of org.apache.apex.malhar.lib.window.accumulation.SumLong in project apex-malhar by apache.
