  • Run parallel tests. Support for Multiple builds where each build can have a defined matrix of instance size's and instance counts.
  • Newrelic for pgsql metrics

#FAQ

  1. How do i run buils in parallel? Each build needs a unique name

  2. I don't want to use Newrelic? If you don't have a newrelic key or don't want to use newrelic, then comment out the newrelic_key variable in file group_vars/build
