processingComplete
public void processingComplete(boolean awaitAdvance) This will decrease the count of waiting parities in phaser reducing the number of processing threads. This should be invoked when processing is complete for the current parser update in a column sink. When all column sinks invoke the method then partition parser updates for the next chunk will be published- Parameters:
awaitAdvance
- a value of true indicates if we should block in this case until all parties arrive
-
hasMorePartitions
public boolean hasMorePartitions()- Returns:
- true if there are more partitions to be processed in the original PartitionParserUpdate published from partition parser
