Hi all,
I am playing around with structured streaming and looked at the code for
ConsoleSink.
I see the code has:
data.sparkSession.createDataFrame(
data.sparkSession.sparkContext.parallelize(data.collect()), data.schema)
.show(numRowsToShow, isTruncated)
}
I was wondering why it does not do data directly? Why the collect and
parallelize?
Thanks,
Assaf.
