It's only reckless if it gets slammed into the baseline without review.
That will never happen;-)

Yes, I saw that a little while back. At first glance, I sure liked it.
I wanted something that used APR (remember the mem usage issue), and
something fairly light weight. Plus, I'm not sure if it was around when
I started my original work. But I would check it out if I were you. If
you look at ODBC/JDBC or whatever, it has a great deal of support for DB
related metadata and other convenient things. This is great stuff for
applications that require runtime schema discovery. A report generator
is a good example of something that needs this type of capability. IMO
Subversion needs none of that. So I tried to keep my work focused on
writing, executing, and configuring hand written queries.

I was just looking for it. It's not in my Subversion repos. Shame on me.
I have it backed up in several places though.

It has nothing to do with MySQL. It's SQL DBs in general. The InnoDB
impl is quite good from what I've seen so far. And I can't say I agree
with the word "unnecessarily".
I will post my doc at http://www.cdrguys.com/subversion/index.html later
today. But, like I said, I'm buried. So please don't expect much more
from me right now. I have enough guilt about my lack of Subversion work:-)

Not at all. From what I've seen, the people on this list appreciate any
and all work being done. Whether it makes it in the baseline or not.
The only other advice I can give right now is: round trips to the DB
Again, way to go folks. I'm very excited about 1.0.
