# .arcignore is the same as .gitignore but for Arc VCS. # Arc VCS is a proprietary VCS in Yandex that is very similar to Git # from the user perspective but with the following differences: # 1. Data is stored in distributed object storage. # 2. Local copy works via FUSE without downloading all the objects. # For this reason, it is better suited for huge monorepositories that can be found in large companies (e.g. Yandex, Google). # As ClickHouse developers, we don't use Arc as a VCS (we use Git). # But the ClickHouse source code is also mirrored into internal monorepository and our collegues are using Arc. # You can read more about Arc here: https://habr.com/en/company/yandex/blog/482926/ # Repository is synchronized without 3rd-party submodules. contrib
