Re: git-svn: Why not use git-fast-import?

I've been playing with git-svn for some time already and as it seems
to me there are two most important problems which make it hard to use
in production for large repositories. Very low speed and large memory
footprint of synchronization with SVN repos (I am talking about clone
and fetch operations mostly). I was wondering why the git-fast-import
is not used for these purposes? Are there any serious limitations
which make it impossible?

The main reason is that git-svn predates the invention of fast-import.
There was an attempt later to make a more "modern" svn interface:

  - it would provide a git-remote-helper interface (so you could use
    normal clone, fetch, and push with an "svn::" URL rather than a
    separate git-svn).

  - it would use fast-import for moving data into git

but it was never finished. I don't recall the specific problems offhand.
You can see the remnants in the vcs-svn directory of git, or you might
find discussions by searching the list archive.
