How Scalable is VoltDB?

Percona guys[1] have run, analyzed, and concluded about VoltDB scalability:

VoltDB is very scalable; it should scale to 120 partitions, 39 servers, and 1.6 million complex transactions per second at over 300 CPU cores

Considering the definition: “A system whose performance improves after adding hardware, proportionally to the capacity added, is said to be a scalable system.”, the conclusion should be slightly updated:

VoltDB can scale up to 120 partitions on 39 servers with 300 CPU cores and 1.6 million TPS.

Bottom line:

  • if you can fit your data into 40 servers’ memory
  • you need ACID and SQL
  • you are OK precompiled Java based stored procedures
  • you don’t need multi data center deployments

now you can estimate how far you can go with VoltDB.
