Things to examine before committing a new feature :

1. OS
   • what will happen in Linux/Win/AIX/POWERPC? (vice versa)
   • Is agent / db on other OSs acts the same? (process per connection, …)
   • Do common parts of the code use os agnostic code ? (types.h, no OS specific API, …)
   • Environments
     • K8S
     • BigData
2. Memory
