I understand that patches to enhance git-svn to allow it to store its
metadata via DBI (as git-cvsserver currently does) would be more than
welcome.
I made an example for an old version of git-svn, which stored the
information in a DBM. However using a set of tables would be much less
of a hack.

Treat that change as a reference only; it just shows what places in the
code would need to be touched to support a different storage format. A
mergeable patch to fix this would probably need to support both methods,
detecting which is available or in use.
Sam.
