Subverion 1.7 Centralized Metadata Storage

Hello all,

Could anyone please explain a little on the following feature?
Specifically, my questions are

* How it affects the current subversion (1.6) features and performance
* This way makes svn git-like :), my first impression is that:
   subversion will be distributed, not centralized :)

Centralized Metadata Storage

A key feature of the changes introduced in Subversion 1.7 is the
centralization of worky copy metadata storage into a single location.
Instead of a .svn directory in every directory in the working copy,
Subversion 1.7 working copies have just one .svn directory—in the root
of the working copy. This directory includes (among other things) an
SQLite-backed database which contains all of the metadata Subversion
needs for that working copy.

Even though the data is stored in a structured format, the relationships
between the data are complex. We highly discourage external tools from
modifying the data held in this database, as such modification is likely
to result in working copy corruption.
