DML drivers
From MoodleDocs
Moodle 2.0
Previous versions were using adodb abstraction partially encapsulated by old DML api. The database drivers are now fully separated from the rest of code and it is even possible to create new native drivers that do not rely on adodb abstraction anymore.
At present there are two sample native drivers - mysqli and pgsql. The benefits are:
- more optimised and probably faster
- consume less memory
- better possibility to improve logging, debugging, profiling, etc.
- less code, easier to fix and maintain
- and more
Please note that native drivers are now used by default in HEAD because we need to get as much testing as possible ;-)
TODO
- add more info here
- add separate docs pages for each driver - describe all options there
