Using `objects/info/alternates`, the source project and forks use the object pool for shared objects. Objects are moved from the source project to the object pool when housekeeping is run on the source project. ```ruby # object pool paths "@pools/#{hash[0..1]}/#{hash[2..3]}/#{hash}.git" ``` -The object pool feature is behind the `object_pools` feature flag, and can be -enabled for individual projects by executing -`Feature.enable(:object_pools, Project.find(<id>))`.
