That’s right, I’m talking about the beast that is cherry picking into upper branches. If you’ve ever played D&D, you’ll understand this tradeoff.īecause these additional branches slow down your development workflow, organizations may be tempted to add more complexity to increase their speed-selecting individual changes to merge into upper branches (in our example, staging and prod), rather than waiting to promote an entire branch. The more layers you have, the harder it will be to move quickly and nimbly on the battlefield, but you’ll also be less likely to sustain injuries. You can think of these additional branches as layers of protective armor. While this approach-often referred to as “continuous delivery” or “indirect promotion”-is more complex, it allows for a higher level of protection for your production code. The entire staging branch is merged into the prod branch.The entire dev branch is merged into the staging branchĪfter a final review of the staging branch:.In this hierarchical promotion, once a set of feature branches are vetted in dev: When ready, open a pull request to merge their changes back into the dev branch.Create a new feature branch directly from the dev branch.To update the prod branch, a developer will: This article is for those who really absolutely must use a multi-environment dbt project.įor example, a single dbt project repository might have a hierarchy of 3 primary branches: dev, staging, and prod. Organizations that use a simple, single-main-branch strategy are (almost always) more successful long term. In order to have more intensive testing and QA before merging code changes into production, some organizations may decide to create one or more branches between the feature branches and main.īefore adding additional primary branches, ask yourself - "is this risk really worth adding complexity to my developers' workflow"? Most of the time, the answer is no. The main risk, however, is that your main branch can become susceptible to bugs that slip through the pull request approval process. Fast promotion process to get new changes into production.If you are just getting started in dbt and deciding which branching strategy to use, this approach–often referred to as “continuous deployment” or “direct promotion”–is the way to go. When ready, open a pull request to merge their changes back into the main branch.Create a new feature branch directly from the main branch.To update the main branch, a developer will: The simplest branching strategy for making code changes to your dbt project repository is to have a single main branch with your production-level code. Why do people cherry pick into upper branches?
