An anonymous reader writes "From Kay Arno's blog we see that David Axmark, MySQL's Co-Founder, has resigned. This comes on top of the maybe, maybe not, resignation of Monty. We saw earlier this year that Brian Aker, the Director of Architecture, has forked the server to create a web-focused database from MySQL called Drizzle. The MySQL server has been 'RC' now for a year with hundreds of bugs still listed as being active in the 5.1 version.
What is going on with MySQL?"

Theoretically, yes you can fork the code. But there are broader issues than the legal ability to fork.
This has put a huge question-mark over MySQL's long-term viability. For a fork to be viable, you need a critical mass of developers. But we've seen 2 key ( founding ) developers leave, and Oracle buy InnoDB.

Don't use stored procedures. They concentrate computation in the database server which is harder to scale than the application servers.
Ahh, sadly this is what "MySQL database thinking" has wrought.
The mystical grail of the enterprise "scaling." Like many things, conventional wisdom often evaporates when confronted with facts. Can stored procedures load the server? Sure, if you are doing something bad. For the most part stored procedures reduce server load.
(1) Stored procedures can be "pre-compiled" SQL which saves CPU time in the planner. (In databases with such an architecture).
(2) Stored procedures allow data selection beyond mere SQL and can lead to the reduction of data transfered from server to application.
(3) In PostgreSQL, for instance, one can create an index based on a function (like a stored procedure), so:
create index on mytable myindex (foobar(mycol) );
select * from mytable where foobar('froboz') = foobar(mycol) ;
Generates a query that uses and index and doesn't do a full table scan.
(4) Computers today are seriously fast, so much faster than the data storage systems that CPU capability is almost infinite with regards to I/O. Any CPU work that can be done at the server to reduce I/O load will probably improve general scalability.
Basically, stored procedures and functions would not exist, i.e. no one would have created them, if they did not help. Saying that "don't use stored procedures because they load the server" is the same logic behind "don't use power tools because they are dangerous." Yes, if you are ignorant, power tools present a huge danger, however, neglecting them means a lot more work. It is better to educate ones self and use the more powerful tools. Those tools would not exist if they did not provide a positive contribution.

Horses for courses, mate. There are good arguments in either direction. Personally I tend to avoid stored procedures not for performance reasons but for pragmatic ones. For one, it's easier sometimes to get a change approved in an application than it is to talk someone into approving a change -- any change -- in the database schema, no matter how trivial, and for another it's easier to migrate or replicate a database to another platform's database (say, Oracle to DB2 for example) when you're only worried about transferring tables and views, not logic. And it is true that the simpler it is, the easier it is to scale. Databases tend to scale by lock-managed clustering, applications by horizontal means (sometimes simply adding another apps server). One tends to be easier than the other.
Sucking data out in bulk can be a good idea too, for safety reasons -- I've seen bank OLTP databases frozen because someone thought it would be safer to set a read-only lock on a report scan, not realising they were using the wrong consistency setting across the entire database & thus forcing the rest of the users (thousands of them) to operate off the DB's log file, then killing the job mid-way after a few hours only to discover he had to face a few hours rollback....
Like I say, horses for courses...

Don't use stored procedures.
That's a very narrow-minded statement. The application I maintain has an Oracle 10g backend, Pro*C middleware, and a Java fat client. The standard process for an action in the application is to ask the middleware to run a certain stored procedure in an Oracle package.
Given that this application is huge (I'm talking 1000+ tables, some with up to a million rows) and there are at least 1000 concurrent users, it's very convenient to have the logic on the server-side. Any code change to the client requires an outage (to replace the jar file), which is BAD if it's an emergency fix. By putting all the logic (and access to a vast amount of data) server-side, it reduces network traffic, allows easy rollbacks, and allows the support team to apply a fix without an outage.
Some more great things about our setup is that Oracle packages and triggers support networking. We have a publish/subscribe system tied to triggers such that when one user makes a change, it's instantly reflected on every other user's screen.
Obviously this solution isn't best for all situations, but it fits our needs very well. YMMV

there's no need to start dicksizing about the type of databases you manage. no one is claiming that MySQL is the best database management system out there, or that it can handle any kind of application. but for a certain range of applications it's a very capable and well designed database server.
not everyone needs a multi-terabyte database. and the utility of a RDBMS is not defined by database sizes it can handle. MySQL is so popular precisely because most sub-enterprise businesses don't need anything as robust as Oracle. so MySQL is therefore a much more cost-effective solution.

Re:MySQL sucks (Score:5, Informative)
Actually there is some relevance.
If you needed a database gigabytes in size a few _years_ ago, MySQL would have been a really bad choice (it still is crap, just less so IMO).
For MyISAM:
You would have to configure it to get tables bigger than the default 4GB limit (there's a number of row limit and table size limit). Hope you don't make the new setting too small so you're still working in the place when those run out too
For Innodb:
Before the single file per table, if you're moving about gigabytes of stuff, you end up with one huge multigigabyte innodb table.
For both:
Adding an index was the same as "alter table" and involved making a copy of the table.
So let's say you have a 40GB table and 40GB of space free. No index add for you
Keep in mind if you have plenty of space free making a copy of a 40GB table does take time.
BTW concurrent inserts to an innodb table with an auto increment field were slow till only recently (well allegedly they've fixed that).

For cost, for robustness, for functionality, MySQL is a far poorer choice than PostgreSQL.
I've used lots and lots of databases, relational and otherwise - MSSQL, Oracle, DB2, Informix, Unidata, etc. etc.. MySQL looks great to people who haven't got much experience with other databases, and it looks like a chunk of shit to those of us who have. I'm not even talking about database size. I'm talking about functionality level stuff - views, useful subselects, a single reliable table type that supports transactional data writing (and for that matter, a transactional layer that isn't shitty). Features that are always coming in a future version, but are already available in other products - ones that can be had for free.
There's no compelling business case for MySQL over another product, except that you might need to make use of a crappy open source project that's tied to it.
