If there is a high amount of such traffic, hitting a Gitaly server with manyĬlones for a large repository is likely to put the server under significant Most git clone or git fetch traffic (which results in starting a git-pack-objects process on the server) often come from automatedĬontinuous integration systems such as GitLab CI/CD or other CI/CD systems. Both memory and CPUĪre heavily utilized during this operation. Repository has and the more expensive this operation is. The larger the repository, the more commits, files, branches, and tags that a Responsible for figuring out all of the commit history and files to send back to The most resource intensive operation in Git is the ![]() You should use as many of the following strategies as possible to minimize ![]() Git are experienced in Gitaly, and in turn by end users of GitLab. Monorepos can also impact notably on hardware, in some cases hitting limitations such as vertical scaling and network or disk bandwidth limits. Git itself has performance limitations when it comes to handling Large repositories pose a performance risk performance when used in GitLab, especially if a large monorepo receives many clones or pushes a day, which is common for them. Impact on performanceīecause GitLab is a Git-based system, it is subject to similar performanceĬonstraints as Git when it comes to large repositories that are gigabytes in Some tools and steps to optimize monorepos.What repository characteristics can impact performance.While they have many advantages, monorepos can present performance challenges Monorepos have become a regular part of development team workflows. Reference architectures Managing monorepos.Here are some example configurations for Azure DevOps and for Jenkins, but I would assume most other CI/CD tools support this. Doesn’t care about the rest of the repository, but only for the latest and greatest.When having only depth 1 you could also save a lot of time when cleaning up your build servers. Using the depth option will also save quite a lot of disk space compared to fetching all of the branches and their history. ![]() How about disk space? I’m sure the DevOps engineers out there are smiling now. Why? Because your build probably doesn’t need all the history, it’s not relevant as it’s using the latest version anyway. Using the depth option for your builds, automations & scripts could be a great solution for minimizing their runtime. Have you ever tried thinking about how to minimize the amount of time the build is running? (If you are a DevOps engineer, I’m sure you did □ ) (‘ bisecting’ your history to find the commit that introduced a bug) Note: Using the clone depth 1 only pulls down one branch, if the remote repository contains additional branches, you won’t be able to ‘checkout’ / ‘switch’ to them.įor a repository you are working on your daily basis you wouldn’t want to perform this shallow option, because you would like to integrate with the rest of the branches (merge, resolving conflicts in advance of your PR) and operate along the history if any issues need to be investigated. ![]() When performing the command without specifying a branch it will bring your default branch, but you can also mention the specific branch you are interested in, for example: Creating a shallow clone - git clone -–depth is a powerful feature by git to reduce the repository size you are cloning to your computer, build server, pipeline, etc.īy specifying the depth of the repository when cloning, you decide how many commits you would like to get from the specific branch to your computer.
