doc/topics/git/partial_clone.md

-# Partial Clone for Large Repositories
-
-CAUTION: **Alpha:**
-Partial Clone is an experimental feature, and will significantly increase
-Gitaly resource utilization when performing a partial clone, and decrease
-performance of subsequent fetch operations.
-
-As Git repositories become very large, usability decreases as performance
-decreases. One major challenge is cloning the repository, because Git will
-download the entire repository including every commit and every version of
-every object. This can be slow to transfer, and require large amounts of disk
-space.
-
-Historically, performing a **shallow clone**
-([`--depth`](https://www.git-scm.com/docs/git-clone#Documentation/git-clone.txt---depthltdepthgt))
-has been the only way to reduce the amount of data transferred when cloning
-a Git repository. This does not, however, allow filtering by sub-tree which is
-important for monolithic repositories containing many projects, or by object
-size preventing unnecessary large objects being downloaded.
+# Partial Clone
+
+As Git repositories grow in size, they can become cumbersome to work with
+because of the large amount of history that must be downloaded, and the large
+amount of disk space they require.
 
 [Partial clone](https://github.com/git/git/blob/master/Documentation/technical/partial-clone.txt)
 is a performance optimization that "allows Git to function without having a
 complete copy of the repository. The goal of this work is to allow Git better
 handle extremely large repositories."
 
-Specifically, using partial clone, it should be possible for Git to natively
-support:
-
-- large objects, instead of using [Git LFS](https://git-lfs.github.com/)
-- enormous repositories
-
-Briefly, partial clone works by:
+## Filter by file size
 
-- excluding objects from being transferred when cloning or fetching a
-  repository using a new `--filter` flag
-- downloading missing objects on demand
+> [Introduced](https://gitlab.com/gitlab-org/gitaly/-/issues/2553) in GitLab 12.10.
 
-Follow [Git for enormous repositories](https://gitlab.com/groups/gitlab-org/-/epics/773) for roadmap and updates.
+Storing large binary files in Git is normally discouraged, because every large
+file added will be downloaded by everyone who clones or fetches changes
+thereafter. This is slow, if not a complete obstruction when working from a slow
+or unreliable internet connection.
 
-## Enabling partial clone
+Using partial clone with a file size filter solves this problem, by excluding
+troublesome large files from clones and fetches. When Git encounters a missing
+file, it will be downloaded on demand.
 
-> [Introduced](https://gitlab.com/gitlab-org/gitaly/issues/1553) in GitLab 12.4.
-
-To enable partial clone, use the [feature flags API](../../api/features.md).
-For example:
+When cloning a repository, use the `--filter=blob:limit=<size>` argument. For example,
+to clone the repository excluding files larger than 1 megabyte:
 
 ```shell
-curl --data "value=true" --header "PRIVATE-TOKEN: <your_access_token>" https://gitlab.example.com/api/v4/features/gitaly_upload_pack_filter
+git clone --filter=blob:limit=1m git@gitlab.com:gitlab-com/www-gitlab-com.git
 ```
 
-Alternatively, flip the switch and enable the feature flag:
-
-```ruby
-Feature.enable(:gitaly_upload_pack_filter)
+This would produce the following output:
+
+```plaintext

 ```
 
-## Excluding objects by size
-
-Partial Clone allows large objects to be stored directly in the Git repository,
-and be excluded from clones as desired by the user. This eliminates the error
-prone process of deciding which objects should be stored in LFS or not. Using
-partial clone, all files – large or small – may be treated the same.
+The output will be longer because Git will first clone the repository excluding
+files larger than 1 megabyte, and second download any missing large files needed
+to checkout the `master` branch.
+
+When changing branches, Git may need to download more missing files.

+> [Introduced](https://gitlab.com/gitlab-org/gitaly/-/issues/2553) in GitLab 12.10.

+CAUTION: **Experimental:**

-## Excluding objects by path
+Deeper integration between Partial Clone and Sparse Checkout is being explored

+### Error installing managed apps on EKS cluster
+
+If you're using a managed cluster on AWS EKS, and you are not able to install some of the managed
+apps, consider checking the logs.
+
+You can check the logs by running following commands:
+
+```shell
+kubectl get pods --all-namespaces
+kubectl get services --all-namespaces
+```
+
+If you are getting the `Failed to assign an IP address to container` error, it's probably due to the
+instance type you've specified in the AWS configuration.
+The number and size of nodes might not have enough IP addresses to run or install those pods.
+
+For reference, all the AWS instance IP limits are found
+[in this AWS repository on GitHub](https://github.com/aws/amazon-vpc-cni-k8s/blob/master/pkg/awsutils/vpc_ip_resource_limit.go) (search for `InstanceENIsAvailable`).

+It is possible to use the GitLab API to purge the dependency proxy cache for a
