I watched it yesterday after seeing a link to it posted on the Fossil-SCM users mailing list; he wrote Fossil to maintain the SQLite code. Awesome material.

Whenever someone says "pls" because it's shorter than "please", I say "no" because it's shorter than "yes".

Thanks jchd, a very information presentation. I especially enjoyed the part about "What if..." git and such like were to move to a SQL database.

SQLite is an awesome piece of code, just as Fossil. Richard is right when he insists that SQLite should be the application data format of choice in many cases. He doesn't advocate this for profit, just because it's plain sensible.

About SQLite being used as a webserver engine, here's what Dr Hipp wrote some time ago answering this question:

> Does people use SQLite for Web development? Or web apps are written

> only with mySQL/MS SQL?
 
« The www.sqlite.org site uses SQLite, of course.  That site gets between
200K and 300K HTTP requests per day, depending on the day of the week.
About 3/4ths of the requests are for static content but the other 1/4th
(23.73% over the previous two weeks) are dynamic content which must consult
an SQLite database, usually via Fossil (http://www.fossil.org/).  The
server is leased from Linode (http:/www.linode.com/) and is a 1/16th slice
of a real machine.  The load average is typically about 0.05.  You can
visit one of the dynamically generated web pages like
http://www.sqlite.org/src/timeline to see that response-time is very fast.
The aforementioned timeline page requires about 102 differ separate queries
to render.

Add this all up and SQLite is doing about 75 queries/second every second,
all day long, on 1/16th of a server with a load average of less than 10%.

That kind of performance covers a lot of websites.

One rule of thumb is that if you and run your website from a single server,
SQLite is sufficient.  If you need multiple servers, then consider a
client/server database engine like MySQL or PostgreSQL. »
