Example 9 with TupleEntry

use of cascading.tuple.TupleEntry in project SpyGlass by ParallelAI.

the class JDBCScheme method sink.

@Override
public void sink(FlowProcess<JobConf> flowProcess, SinkCall<Object[], OutputCollector> sinkCall) throws IOException {
    // it's ok to use NULL here so the collector does not write anything
