Debunking Myths about the VoltDB in-memory database

I’d like to take a quick moment to address some myths and misconceptions about VoltDB. Many people selling products who view VoltDB as competition seem to be repeating them. As you’ll read, much of what’s said is just plain FUD.

VoltDB is an in-memory database that has benchmarked at over 3 million transactions asecond on bare metal, and recently crushed previous performance records in the cloud, posting eye-popping YCSB (Yahoo! Cloud Service Benchmark) numbers on AWS, Amazon’s cloud platform.

Target audience

This post targets other VoltDB developers who are going to be dealing with the various unconventional ways Volt now uses native memory in the Java portions of the database. It will also be of interest to other Java developers looking to step outside what is typically considered Java’s comfort zone for interacting with native memory.

What was

Out of the box Java doesn’t give you much in the way of tools for accessing native memory allocation and deallocation mechanisms like mmap or malloc.
