The “dolt fetch” command is a feature provided by Dolt, a version-controlled database system inspired by Git. The “dolt fetch” command allows you to download objects (such as commits, tables, and data) and refs (such as branches and tags) from another Dolt repository.
Here are some key aspects of the “dolt fetch” command:
- Fetching changes: When you execute the “dolt fetch” command, Dolt contacts the remote repository specified as the upstream and downloads any new commits, tables, and data that exist in the remote repository but are not present in your local repository.
- Updating refs: Along with fetching changes, the “dolt fetch” command also updates the remote refs (such as branches and tags) in your local repository to match the state of the remote repository. This allows you to track the latest changes made by others and synchronize your local repository with the remote repository.
- Remote tracking branches: After fetching changes, Dolt creates or updates remote tracking branches in your local repository. These branches are prefixed with the remote repository’s name and can be used to reference the corresponding branches in the remote repository.
- Merging fetched changes: Fetching changes does not automatically merge them into your working branch. After fetching changes, you can use the “dolt merge” command to incorporate the fetched changes into your local branch, ensuring that your working branch reflects the latest state of the remote repository.
- Collaboration and synchronization: The “dolt fetch” command is essential for collaborating with others and keeping your local repository up to date with the latest changes made by team members. It allows you to download and integrate changes from a remote repository, ensuring that everyone is working with the most recent version of the database.
By using the “dolt fetch” command, you can retrieve new commits, tables, and data from a remote repository and update your local repository accordingly. This enables you to stay in sync with the latest changes made by others, collaborate effectively, and ensure that your local database is up to date.
Please note that the specifics of the “dolt fetch” command, such as available options or additional functionality, may vary depending on the version of Dolt you are using. For detailed and up-to-date information, it is recommended to refer to the official Dolt documentation or use the “–help” flag alongside the command to access the command-specific help information.
