One-line Summary

Spark is a generalized MapReduce model (in-memory Hadoop :P). It uses RDDs to support in-memory computations.

Background & Motivation

  • Programmability

    • Most real applications require multiple MapReduce stages:

      • Google indexing pipeline: 21 steps

      • Analytics queries: 2-5 steps

      • Iterative algorithms: 10s of steps

    • Multi-step jobs create spaghetti code

      • 21 MapReduce steps -> 21 mapper & reducer classes

  • Performance

    • MapReduce only provides one pass of computation (must write data to file system in between)

    • Expensive for apps that need to reuse data (e.g., multi-step algorithms like PageRank, interactive data mining)

Design and Implementation

Apache Spark

  • Simple, functional API

    • 5x - 10x less code than MapReduce

    • Parallel transformations on collections

    • Available in Scala, Python, Java, and R

    • Can trace how operations are chained -> free type checking!

    • Mimics local programs

  • Performance

    • In-memory computing primitives

      • In-mem caching: LRU

      • Caches also get cleared when workers go away

    • Optimization across operators

  • Lazy evaluation/execution

  • Fault tolerance

    • Lineage graphs: Records of transformations that created this RDD

      • Assumption: Input file is still available

      • Assumption: Storage for lineage graphs is stable (similar to the MapReduce master)

  • Job scheduling

    • Captures RDD dependency graph

    • Pipelines function into "stages"

    • Cache-aware for data reuse, locality (move computation to where data is cached)

    • Partition-aware to avoid shuffles

RDDs

  • Immutable, partitioned collection of objects

  • Can be cached in memory for faster reuse

  • Operations on RDDs: Transformations (build RDDs) & Actions (compute results)
