Using the row buffer in Drizzle (and MySQL)
+1 Vote Up -0Vote Down

Here’s another bit of the API you may need to use in your storage engine (it also seems to be a rather unknown. I believe the only place where this has really been documented is ha_ndbcluster.cc, so here goes….

Drizzle (through inheritance from MySQL (http://mysql.com)) has its own (in memory) row format (it could be said that it has several, but we’ll ignore that for the moment for sanity). This is used inside the server for a number of things. When writing a Storage Engine all you really need to know is that you’re expected to write these into your engine and return them from your engine.

The row buffer format itself is kind-of documented (in that it’s mentioned in the MySQL Internals

Building MySQL Server with CMake on Linux/Unix
Employee +4 Vote Up -0Vote Down

CMake is a cross-platform, open-source build system, maintained by Kitware, Inc.

From the CMake.org home page:

CMake generates native makefiles and workspaces that can be used in the compiler environment of your choice.

It has been used for building the MySQL Server on Windows since MySQL 5.0 – the initial CMake build support was added in August 2006.

I suppose I should make it official: 2010 should see me being much more active in the Community.Why?

It has been more than a year since my self-imposed hiatus from serious MySQL development started and I think it is about time that I get back into the saddle. I have a handful of working prototypes but I should get the code out there, back into the community.I learned a bunch of stuff during the past year at Google but in the end, working on JavaScript, HTML/CSS and Google proprietary languages
MySQL Error of the day
Employee +3 Vote Up -0Vote Down

Just spotted the following posting from Paul DuBois on the internals mailing list:

I'm engaged in a project (WL#3403) to compile information that will provide better information about our errors and error messages:
  • What an error means
  • Likely causes of the error
  • How to rectify or work around the error

The general idea is to provide our users something more than a list of error codes and the messages from errmsg.txt, such as the manual currently includes here:

Perl and Java Stored Procedures for MariaDB 5.1
+1 Vote Up -0Vote Down
I just applied the external stored procedure patch to a branch of MariaDB and uploaded it to LaunchPad.You can see the branch at https://code.launchpad.net/~atcurtis/maria/5.1-wl820Note that this is not in any reasonable condition to merge into MariaDB. Hopefully we can engage in dialog as to how we can bring this feature properly to MariaDB, MySQL and Drizzle, hopefully making the plugins

Files used in conference presentation here: UC2009 presentationI think todays presentation for Perl Stored Procedures for MySQL was quite successful. The audience was quite engaged and asked questions throughout (yes, I invited questions through the talk).
