Hey,

In Apache Spark, the data storage model is based on RDD.

  • RDDs help to achieve fault tolerance through the lineage.
  • RDD always has information on how to build from other datasets.
  • If any partition of an RDD is lost due to failure, lineage helps build only that particular lost partition.
