Exporting large survey
Hi guys,
We are running our own JATOS server on Digital Ocean. When we try to load a study with many results (~800), we get stuck here:
Can't tell if this is failing because it's large or what might be happening. On the Digital Ocean side, I can see that it was doing something but is tapering off and not updating on the website:
Any suggestions? Do I need to download the data from the linux terminal manually instead? (I saw this somewhere else but now can't find it, can you direct to me directions for this if necessary?). Thanks!

Hi!
Yes, you are right loading of all study results fails because there are too many data. The underlying reason is that JATOS loads (actually not JATOS but a library called Hibernate) all data first into memory and only then sends them off to the browser. But since version 3.5.9 JATOS has a workaround for this. Can I assume you are using a version before 3.5.9? If yes, please update and try again. And I recommend using Chrome for large datasets: it's faster and uses less memory in the browser.
Best,
Kristian
We are using 3.5.8 - let me do a quick backup and update to see if that solves the problem.
That definitely solved it - thank you!
