Hi Kalyan,
Event support is already there in mariadb. Events are the jobs which are run in certain time interval. I am asking about a new project idea which is mentioned in mariadb gsoc page. It is unclear to me, what are the use cases of user defined events( Events and user defined events are not the same, simply because it is mentioned in the page as a new project idea. :) )
As far as I know user defined events are supposed to save applications resources used in polling. But I think the application developer could have created a trigger and udf and use
lib_mysqludf_sys to invoke external application. But there are security issues in this method. Is it the primary/only reason for this project?
