Benchmarking

Workload

• Keyspace: collection of keys; each key is a number (as Java String)

  • Fixed: [0, 1000)

• MPL (Multi-Programming Level): the number of concurrent clients that are submitting transactions

  • Variables: in (1, 3, 5, 10, 20, 50, 100, 150, 200)

• Number of transactions issued by each client

  • Fixed: 1000

• Size of transactions: number of keys accessed

  • Distribution: ???

• Read/Write ratio in each transaction:

  • Variables: 1:1, 1:5, 1:10, 5:1, 10:1

• Keys to operate on:

  • Distribution: Zipfian distribution to separate the "hot" keys; ZipfianGenerator.java@brianfrankcooper/YCSB with parameters [0, 1000)

• Transaction inter-issue interval

  • Distribution: exponential with fixed lambda parameter 500ms

RVSI specification

• RVSI parameters:
  • k1:
  • k2:
  • k3:

Measurements

• Abort rates
  • impact of RVSI parameters and MPL
• System throughput: overall transactions/seconds
