Thread: Wisconsin Circuit Court Access (WCCA) on PostgreSQL

Wisconsin Circuit Court Access (WCCA) on PostgreSQL

From
"Kevin Grittner"
Date:
The Consolidated Court Automation Programs (CCAP) of the Wisconsin Court
System has migrated to PostgreSQL for all of its Circuit Court web
operations.  Eight production databases have been converted, six of them
around 180 GB each, holding statewide information replicated real-time
from 72 county databases.  The central copies support audit functions,
statewide statistics and report generation, and this web site:

http://wcca.wicourts.gov/

Given the success of this effort, we expect to be converting the other
court databases to PostgreSQL.

We've been very happy with both the performance of the product and the
support we have received from the mailing lists.  Overall, PostgreSQL
has been faster than the commercial product from which we converted.
Even more important is the fast response we have had when posting
problems to the lists.  We have normally had a fix within 24 hours.
Frankly, the support has been amazing.

We wonder how widespread the use of PostgreSQL is within government
agencies; I would love to hear from anyone with experience with this.
With tight budgets, it seems likely that there may be others moving in
this direction.

This is way cool.  Do we have permission to quote you on the PostgreSQL
home page?

There are.  Unfortunately, a lot of them are in Defense or Homeland
Security, which means that they will never go on the record about what
software they use.  Publically known users include:

Library of Congress
California Attorney General
National Gallery of Art
City of Garden Grove
National Weather Service
NOAA
Lawerence Berkeley Labs
University of California
U.S. Army
Gov't of Venezuala
Sao Paolo Metro
San Francisco MUNI

... and a bunch more I can't remember right now ...

Always good to hear. Two obvious questions:
1. Have you completed a case-study questionnaire (and if not, would you
be prepared to?)
2. People on the advocacy lists occasionally get asked for
quotes/interviewees by the press. Would you be up for this?

You can spend more time on hold calling commercial vendors than it takes
to get a patch with PostgreSQL :-)

Kevin, well done. We've all watched your progress with interest.

The reason you've got excellent support is because of the detailed
postings you've made, together with responses to all replies. Doing all
your homework before posting is essential; unfortunately many people
don't do this and then leave disappointed.

Best Regards, Simon Riggs

Thanks to all who have offered congratulations.

Here I think you underestimate how well the community helps people in
these lists.  I have witnessed remarkable patience here when people post
vague messages asking for help.  You (as a community) generally succeed
in drawing out sufficient detail to provide good advice, and / or
identify areas for product improvement.  I do try to give as much
information as I can, including reproducible test cases where
practicable; but, I have done so with commercial vendors to whom my
clients have paid big money for support, and been very disappointed.

With one commercial vendor we've routinely been told by first line
support staff that the product was functioning as intended.  After days
of effort, sometimes involving calls from top management, we've gotten
through to someone who can actually understand the problem and
acknowledge the bug; only to have it take months (sometimes over a year)
to get a fix,

With another open source vendor, from whom no support is available
without a paid license and a paid support contract, we (after paying for
a commercial license and a support contract) have been told that such
things as using an OR predicate within the ON clause of a JOIN was an
"unimplemented feature" (even though it worked in simple cases).  They
said they might "add the feature" in the next major release, but that
wouldn't be for at least a year, and no guarantees.

It was unexpected and quite refreshing to provide the same level of
detail in a post to a PostgreSQL list, and get a patch file fast enough
to be running a fixed version within 24 hours of posting the problem.
When we have been able to provide sufficient detail and / or a test
case, this has usually been the result.  When we participated in the
beta test phase, people were quite helpful in leading me through the use
of unfamiliar tools to capture the information they needed to identify
and fix problems before the official release.

After decades of working as an independent consultant, I've recently
(eight days ago) accepted employment with the Wisconsin Court System as
a DBA, and I'm told that as a court employee I'm not allowed to endorse
one product over another; but, I can speak of my experiences with
products so long as I don't violate any constraints of the license
agreements.  I have worked with quite a few database products in my
career and can say unequivocally that the support I've seen provided for
PostgreSQL is superior to that which I've seen provided for any other
database product.

I don't want to name any names, because I would undoubtedly forget
several very helpful people here, but I have to admit that my personal
favorite was when I posted information about a bug in the JDBC driver
shortly before I left for the day, and while I was sleeping a user in
Germany created a program to cause the race condition, tracked down the
cause, and posted a patch with a suggested fix.  By the time I'd
finished my coffee the next morning, the patch had been reviewed, scaled
back to the minimum change required to effect a fix, applied to CVS, and
a new jar file deployed for download.  Wow.

I can't really accept congratulations for this successful deployment
without offering it right back to the community for all the help you've
provided, as well as the product itself.  Absolutely fantastic, all
around!

If we do not have a testimonilas page, then  this is the perfect example of
why we should, and what should be on it.  As good as we are in features, text
like this can be far more efective in getting a foot in the door with PHB.

(just my 2 bits worth)
