How to make aggregation in Jira ?

Question

Hi,

In JIRA, i need to aggregate dimensions and to apply specific methods to measures (which is not curently supported by the commercial add-on Report ). For example, i want to display all my project and the time spent on these projects. The time spent should be the sum of the time spent on each issues of the project.

According to me there is two ways of doing it:

_ the first is to fetch the lists of all issues and to perform the aggregation on the server (which is clearly not the best idea because Jira simply isn't designed for massive data dumps).

_ the second is to use OfBizDelegator to get a Connection in order to perform a sql request . (with a group by clause). But this seems decried by some develpers.

So my question is : what methods should i pick ?

Thanks in advance.

I don't actually know. If I was to guess then I would say: performance reasons. I imagine doing aggregations is hard to make efficient.

This is a question better directed at the JIRA team.

You should be able to do this with the Better Excel Plugin:

* Dump the data to a worksheet and use pivot tables for aggregation (and let Excel do the heavy lifting)
* Consider using pivot charts to visualize the aggregation
* If you wanted to get the input data directly from the database, instead of accessing issue fields, then write a Groovy script that connects to the database, run your query and convert the result set to Excel cells

You have insane flexibility with these techniques:

Thank you for your answer, now i get it. JIRA don't propose aggregation tools or anything close to a group by clause. Still it's bothering me, why not ? It's a really common fonctionality. I searched around and could not find any satisfying answer. Do you have any idea why?

Thanks in advance.
