Max Projects and Issues Per Project

[Mitchell Mudd]

Question 1: Is the max issues that will show up on a kanban board 5000?

Question 2: Is the max number off issues that can be on a project fairly unlimited 50,000+?

Question 3: What is the max number of projects we can nest within a projects by use of a JQL filter board?

We're working a project that involves a project for each building we're doing and roughly 200-300 tasks for each of the projects. They all need to go onto the same board which would mean 300-400 projects on a filter board in one project.

We would most likely not show ALL issues at the same time, but I was hoping to get some insight from the community on some possible best practices for this :)

The max limits are way higher than anyone is likely to reach and will be limited by the largest number issuenum field can hold - 9223372036854775807 in a long?

Are you saying 200-300 tasks in each of 300-400 projects?

When you get to large number of issues on a board, it will really slow down due to the rendering required as well as the volume of data to return. We have boards with 3000+ issues that are already pretty unusable.

It's not what a board was designed for. And then there's the real world.

I would recommend you add some clause to the query to reduce the volumes displayed in a board: resolved empty or less than 7 days ago ?

Maybe push into the backlog so it's not on the main board.

To query a lot of changing projects I use category field. It can be set on each project. You JQL can then use:

category = MyBucket ...

Unless category is already in use by your site

Whoa that's a lot of issues! 

I think applying to default queries to keep the results on boards to a minimum makes sense :)

We are using a category right now for all of the projects - Do you know of any limit on the number of projects that can be pulled into a board that way? I had read 100 was the max, but didn't know if that was old information

Thanks for your response!

There is a limit on roadmaps of 5000 issues and 100 projects. And of 1000 issues if you export query results.

Apart from that I am not aware of any limits being applied.

Labels are also a useful 'cheat' I've used for pulling in issues from multiple projects

Good to know, thanks for all the help Tom!
