Instead of sending a copy of the data with every task, Spark keeps a read-only version on each machine. These datasets are inherently fault-tolerant, as Spark automatically records the lineage of operations used to build them.

Broadcast Variables When a small dataset needs to be used by all executors, broadcasting it saves network bandwidth. If a partition of data is lost, Spark can reconstruct it using the original transformations.
