Amit Jain commented on OAK-7722:
--------------------------------
[~frm], [~mduerig] Would something like this work - [^OAK-7722.patch]? My limited tests with [https://github.com/apache/jackrabbit-oak/blob/trunk/oak-run/src/test/java/org/apache/jackrabbit/oak/run/DataStoreCommandTest.java] are good.

> Currently, to collect all external blob references for the {{Mark}} phase of DSGC, we need to open the segment store in a read-write mode i.e. use FileStore instead of a ReadOnlyFileStore. The task is to implement the \{{collectBlobReferences}} method in the \{{ReadOnlyFileStore}}.
> The references being returned might be somewhat stale in this case but by not much.
