Examples with SimpleTimerService org.apache.flink.streaming.api.SimpleTimerService used on opensource projects

Example 1 with SimpleTimerService

use of org.apache.flink.streaming.api.SimpleTimerService in project flink by apache.

the class AbstractPythonStreamGroupAggregateOperator method open.

@Override
public void open() throws Exception {
    // The structure is:  [type]|[normal record]|[timestamp of timer]|[row key]
    // If the type is 'NORMAL_RECORD', store the RowData object in the 2nd column.
    // If the type is 'TRIGGER_TIMER', store the timestamp in 3rd column and the row key
    reuseRowData = new UpdatableRowData(GenericRowData.of(NORMAL_RECORD, null, null, null), 4);
    reuseTimerRowData = new UpdatableRowData(GenericRowData.of(TRIGGER_TIMER, null, null, null), 4);
    timerService = new SimpleTimerService(getInternalTimerService("state-clean-timer", VoidNamespaceSerializer.INSTANCE, this));
    initCleanupTimeState();
    super.open();
}
