Parallelism in DB Operations

Different types of parallelism in DBMS operations
  • intra-operator parallelism
    • get all machines working to compute a given operation
      (scan, sort, join)
  • inter-operator parallelism
    • each operator runs concurrently on a different processor
      (exploits pipelining)
  • Inter-query parallelism
    • different queries run on different processors
