As part of my GrowthBook POC, we set it up growthbook instance on a EC2 instance, with little to no modification of the

docker-compose.yml

that came with the git repo. And we defined data sources and metrics using the web UI forms. I am guessing that all the meta data is being stored in mongoDB. However, when we restarted the docker container using the following commands , I lost all the metrics, exposure and other definitions. I also lost users who registered. I am sure there is a better way to stand it up so as to persist across restarts? Any suggestion is appreciated

docker compose up

I am struggling with specifying the required ID attributes for A/B testing. Should user view the same variation when he logs out if I specify both id (from db) and deviceId (random hash)? I tested and see that variation is not consistent when id changes but deviceId is same

Hi! I have a problem in release build of Android app, when i test debug version all work fine and I can retrieve my configuration data from feature.value field. But when I prepare release build for store, I always receive null inside feature.value field. Can you suggest what could be the problem? Thanks.

Hey guys, I am experimenting with GrowthBook for feature flag experiments on android, and I seem to have hit a roadblock. I have created a feature, set up an experiment that affects all users, split them by

id

, 50%-50%, and whatever I do, I only seem to be able to receive

defaultValue

, instead of the expected overrides (all the users are included in the experiment). Details in thread, do I miss something?

Hi, I am using Next.js middleware for the implementation i.e. Both feature flags and A/B testing based on this article https://dev.to/jdorn/ab-testing-with-the-new-nextjs-12-middleware-54j6. is there a way to use/enable feature flags to render elements or components in the frontend since all the implementation is done in middleware.

Hello, everybody! I'm new in Growthbook and I'm doing some research to my organization and I wanted to understand how often can I refresh cache. I'm looking in docs, but I still haven't found something about this. Could you guys help me?

Hi everyone! I was wondering is it possible to replicate hashFnv32a function that is used in GrowthBook SDKs in SQL, for example in PostgreSQL? I'm thinking of querying against tables with ab tests results. Thank you.

Hi, any tips on how would I go about configuring a holdback group of users that would be excluded from all experiments for a given time period? The idea is that at a later stage this holdback group will be divided to a treatment group receiving all changes at once and a control group -> we could measure first each experiment on it's own and then later measure the combined effect of multiple changes

Hey! I was wondering if anyone tried implementing Growthbook while using Varnish in front of the application server, whilst keeping the logic server side, I’m having trouble to conceptualise it.

Hi everyone Im having trouble setting up experiments with growthBook. My app has a postgres database where all data is stored and we use mixpanel for event tracking. When I try to set up an experiment I get the error "relation "viewed_experiment" does not exist" , but I dont know why growthbook is trying to find that table? I never created or anything and in the docs theres nothing about it
