Hello, everyone. Could anybody tell me, where I can input variable IMPORT_LIMIT_DAYS for resizing window of data collection from my datasource?

That is an environment variable, so you'd need to define it in your environment before starting GrowthBook. It's used when you import past experiments, to limit how far back GrowthBook will look. Is that what you're trying to do?

@strong-mouse-55694 I tried to write it in docker-compose file in enviroment section, but nothing was changed. And now I don't understand where I should write it. I use self-hosted version. Could you send any example pls?

Check this out: https://docs.growthbook.io/self-host/env Let me know if that works for you!
