The only open source software which is remotely similar to InfiniSQL is MySQL Cluster. I believe that InfiniSQL scales and performs better than MySQL Cluster for many operations, especially transactions that contain records on multiple nodes. But, I have done no direct apples to apples comparisons between InfiniSQL and MySQL Cluster and welcome any data to that effect. I may do such benchmarking in the near future, as time allows. The purpose of this article is not to disparage MySQL Cluster (or any other product), but rather to explain the advantages of InfiniSQL, and what sets it apart.
