How to rollback changes of the data base

Hi all,

we are planning to use Gatling to run automatic load tests for our micro-services. The project is composed of about 20 micro-services and we
We intend to integrate Gatling in Jenkins, this is the target workflow:
-deploying the new version of the microservices (on a dedicated environment for load testing)
-run galting tests
The data set used for the tests (accounts, users, …) will we be prepared in csv files committed on git

The next time, when deploying a new version, we will use the same data set (post the same account, same users …)
Our issue is how to rollback/ reset the db to all the data changes after each execution to ensure next execution won’t fail because of data integrity constrains and to ensure data volume stability.

Thnaks, alot ,
Kind Regards,
