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<https://github.com/mysqludf/lib_mysqludf_sys#readme> to invoke external application. But there are security issues in this method. Is it the primary/only reason for this project? On Sun, Mar 9, 2014 at 12:15 AM, Kalyankumar Ramaseshan < rkalyankumar@gmail.com> wrote:

Hi,
what is the difference between a trigger and user defined event?
In postgres there is a clear distintion between trigger and event trigger. Triggers are activated when DML statements are executed whereas
event triggers are activated when DDL statements are executed.
But in soliddb (from which our post in JIRA page is inspired), it seems
like user defined events can be activated for DML statements. What is it that can't be done with triggers and can be done with user defined event?
Why is the restriction that events can only be posted and received by
stored procedures only?
Cheers, Savita
