> Checkpointing is used to cut long lineage while maintaining fault tolerance. The current implementation is HDFS-based. Using the BlockRDD we can create in-memory-and-local-disk (with replication) checkpoints that are not as reliable as HDFS-based solution but faster.
> It can help applications that require many iterations.
