Data export: memory usage and export location

[jonsbun]

I have a few questions about CloudBeaver (v24.3.1) data export functionality:

1. It looks like memory is not released after table export (JAVA_OPTS=-Xmx8g). That leads to OOM during the next data export. I am running CloudBeaver in the Kubernetes environment.
   

2. In DEBUG logs, the export location is set as /tmp/dbeaver/.work-data/data-transfer/124rpl6u8fpbhj4j7xq7b5290_794327ee-efe3-4686-8251-09935a5e80ac.csv. How to set data export location to /opt/cloudbeaver/workspace/.work-data/data-transfer?

Hi @jonsbun
Thank you for your report, we'll take a look!

To point 2: you can change system property java.io.tmpdir to /opt/cloudbeaver/workspace, but then all temp files will be stored in /opt/cloudbeaver/workspace/dbeaver/.work-data/data-transfer

Hi @jonsbun.
I do not think the issue is directly related to CloudBeaver. I am inclined to believe that the problem is caused by allocating all available RAM to the Java Heap by setting JAVA_OPTS=-Xmx8g. As a result, the Java application consumed all available memory and crashed with an OutOfMemoryError (OOM). I would recommend setting the maximum heap size to approximately 6GB instead or even less.
