Hi Team, I had a quick question on re-ramping experiments. Based on the wiki here, we figured that re-ramping an experiment would re-bucket the users with a new experiment key. I do see a new experiment key after the re-ramp with a <test_name>

-re

appended.. But in the data warehouse we still see traffic with old name <test_name>.. Is this expected ? We were trying to find traffic with the new key but no data was found.. Wanted to confirm if using the old experiment key would still re-bucket the users..

This is the right channel. I think we need some more info on how you re-ramped. Here's some general info on making changes to experiments that might be helpful: https://docs.growthbook.io/app/making-experiment-changes

Let me get back to you on this

sounds good

So just checked with our engineers.. 1. In our case, we had deleted previous experiment 2. started a new experiment with same name and ramped it up Wanted to understand couple of things. Based on my reading - 1. hashing algo uses experiment_key_id and unit_id (user/visitor) 2. When we re-bucket users into the experiment, we should either a. create a New Phase b. create a new experiment_id right ?

A lot's going to depend on why you're creating a new experiment. What's the reasoning there? Also, the hashing algo will fall back to the experiment.key, but it'll use a generated UUID (seed) by default.
