# Context
We want to upgrade our existing Satis repository. We currently use it to proxy packagist.org as a public proxy and to host some internal packages.

Due to the very long time it takes to reindex all packages (~30min), we worked around Satis by using GitLab to host some packages (Centrifuge, Heap, Tycoon among others). It works well but has a limitation: it can only store the latest revision of a branch: https://gitlab.com/gitlab-org/gitlab/-/issues/288033

# Options

## Update Satis

https://github.com/composer/satis

We need to evaluate if we can use "partial updates" to reduce build time when building a single dependency: https://getcomposer.org/doc/articles/handling-private-packages.md#partial-updates
We would probably need to use a webhook to trigger the partial update: https://github.com/adanlobato/satis-webhook
