Recipe for conference talks: add a buzzword like "sharding" and show how mysqlnd helps you with asynchronous queries. Only two PHP database extensions give you asynchronous queries: mysqlnd and Postgres. Slides (OpenOffice) from the International PHP Conference 2008 have the details about the asynchronous query API in ext/mysqli (using mysqlnd).

BIT and CPU squeezing with Facebook, Tuenti and Andrey - for the die hard experts… The MySQL Client Server Protocol supports two flavours of sending database results to the client send as text and as binary. Unlike the text protocol, the binary protocol avoids converting data into strings whenever possible. For example, the binary protocol send a TINYINT column value as one byte and not as a length coded string of a length of one to four bytes. This saves CPU cycles on the server by avoiding a cast operation and it saves at least one byte of network traffic - sometimes. Furthermore, ext/mysqli will use an (PHP) integer variable instead of a string to hold the column value. This saves memory when caching database results in …

[Read more]On monday I gave a presentation at MySQL user group meeting in Hamburg on the team I’m working for: the MySQL Connectors team. The presentation was given in german. Unfortunately about 99.99999% of all PlanetMySQL had no chance to join the meetup, but you can find the slides (german language) here for download (PDF). The slides give an overview on the team, its products and its activties. You will also find introduction material on those Connectors (drivers) I am working on: Connector/OpenOffice.org, Connector/C++ and all the PHP stuff.

I have not been giving any Community presentations since 2003, be gentle… Credits to:
While Andrey made good progress with the Connector/OpenOffice.org I wasted my time trying to use OpenSolaris 2008.05 as an OpenOffice.org development platform. OpenSolaris is not on the list of platforms used my the maintainers and developers of OpenOffice.org. Another open technology - JDK 1.5 - has lowered my openness towards new development platforms.
If you are an OpenOffice.org end-user, skip this blog posting: grab a binary package and be happy! That’s better for the world-wide climate because your power consumption will be lower. An Intel Core 2 Duo E6750 …
