We’ve launched a new Size Calculator for Apache Cloudberry to help with hardware planning before starting a POC. Enter your uncompressed data size, choose a physical, VM, or cloud deployment, and get an estimated configuration covering nodes, CPU, memory, storage, networking, and primary/mirror layout. Advanced options also allow you to adjust compression ratio and query concurrency. It’s designed to provide a practical starting point for POC planning—not a replacement for workload validation. Try it here: cloudberry.apache.org/sizing Many thanks to @Ryan Wei for providing the prototype and the original idea!
