GitCentric reflects the flexibility of both the Git and AccuRev environments, and it is possible to configure your repositories and streams in countless ways. However, we recommend keeping the following thoughts in mind:
Therefore, you probably do not want to create a repository that maps to an entire depot. You want your Git branches to map to directories within AccuRev streams that contain smaller, independent sections of functionality.
As with any new tool, it is important that you first understand what your current process is. If you are an existing Git shop, make sure that you have a clear picture of how your repositories and branches are configured, and what your workflow is. In evaluating this, you may find that you need to better define your current environment. If you have never gone through this exercise, consider searching for the following terms on the web: git, workflow, and model. This will point you to some good discussions about successful Git implementations. Once this is done, then you will be in a better position to decide how to map your branches to AccuRev streams.
Also, remember that both Git and AccuRev bring different strengths to your organization. Git provides a convenient, distributed version control system to your development end users. AccuRev provides powerful, centralized version control for users such as build administrators, release engineers, product managers, etc. Git branches can be somewhat transient -- if you start to develop something on a branch and then change your mind, you can delete the branch. AccuRev is TimeSafe, meaning, all versions and transactions are captured permanently in the AccuRev database. When carefully planned, mapping between these environments means that GitCentric provides the best of both worlds to your organization.
