Accumulators tend not to change the lazy evaluation model of Spark. If they are being updated within an Procedure on an RDD, their price is simply up to date when that RDD is computed as Portion of an action.

The textFile approach also usually takes an optional 2nd argument for managing the number of partitions on the file. By default, Spark creates a single partition for every block from the file (blocks currently being 128MB by default in HDFS), but you can also ask for an increased number of partitions by passing a larger price. Take note that you cannot have less partitions than blocks.}
