So, in going around the room at mysqlcamp this morning, only one person mentioned having using another database (SQL Server & Sybase). Another mentioned Access…..but that’s not a “real” database.

But many people mentioned connections to Oracle — be it “used to work for Oracle” or “used to use Oracle”. I think this speaks to how similar Oracle and MySQL are. Now, there are PLENTY of differences. But compared to Sybase, Microsoft SQL Server, Ingres, Postgres and IBM DB2, it sounds like MySQL and Oracle are closer to each other than MySQL and any other database.

Small but good interaction with Bill Karwin of Zend, Taso Du Val of Fotolog and others during the MySQL Camp session on mysqlnd native PHP driver that I’ve blogged about earlier.

Ulf Wendel of MySQL will soon be posting a survey on the new API calls to mysqlnd, so stay tuned for that.

These are tools written at Google that are frequently used, and perhaps useful for other folks.

I'm taking notes from the MySQL core kernel talk:

The core has an architecture like:

Parser Optimizer Storage Layer The storage layer has a Handler and Handlerton. Handlers are the real storage engines but Handlerton is new in MySQL 5.1.

On startup MySQL calls main() and then a plugin init.

The plugin has a UDF handler for user defined functions. It also has a fulltext handler which was originally written for CNET. The fulltext handler allows one to parse out all BLOBs sent to the database. This seems like a cool way to add Lucene support to any type of MySQL storage engine.

There's a new super cool plugin named Daemon which one can use to embed daemons within MySQL. For example someone embedded Apache as a Daemon plugin so that you could get "show processlist" as XML via HTTP. The were going to call this raw but it was too …

Here’s a very rough pre-release of NdbObject, an ORM mapping for python that maps Objects to NDB directly with no SQL code.

At MySQL Camp (over 200 registered participants!), one of the first sessions was lead by Jay and themed “Measuring the MySQL Community”.

The purpose of having MySQL community metrics is to know how MySQL is serving its community. At which rate is it growing? Or is it shrinking? Ideally, we would be able to say “in October 2006, the number of installations of MySQL grew by 3,2 % from 10 340 455 to 10 671 350 installations” and “the community activity index grew from 10,4 to 10,8“.

There are built-in problems with this, though. While we know that we have over 10M yearly downloads, we don’t know how many of those are in active use. And we know many get their MySQL packages from distributions.

Sheeri Kritzer proposed making a the server “scorebord” public. Basically, SHOW STATUS information would be aggregated as a service …

When Jeremy left yahoo a lot of people were left wondering “who would be the next Jeremy?” some people thought it would be me. Since then I have been asked several times why I’m not going to take a turn in the ivory tower. Now that things are in place the secret can be let out. Jeremy’s startup Proven Scaling is not just Jeremy’s startup but our startup. We have decided to take our MySQL skills and apply them to the problems of several companies.
