Problem statement

We have a swagger.json file that has grown to 2.2MB over time and now calling swagger generate is causing the process to use close to 4GB of RAM. Just over a year ago it was under 2GB. We have been allocating more RAM to our containers to mitigate the issue but we are concerns that the process seems to be using a lot more RAM than we would expect. The swagger validate command stays under 500MB and this is not a problem.

Unfortunately we cannot share our swagger.json file but were wondering if others experience the same problem and how to mitigate it.
