> {{SparkSQLOperationManager}} uses {{RDD.toLocalIterator}} to collect the result set one partition at a time. This is useful to avoid OOM when the result is large, but introduces extra job scheduling costs as each partition is collected with a separate job. Users may want to disable this when the result set is expected to be small.
