Temporary storage

How does temporary storage work?

The default directory is /tmp within the pod. If you are using scripting or extension nodes, you can write temp data to /tmp/scratch. You're responsible for securing your temporary storage.

SPSS Modeler temporary storage uses ephemeral storage without any limits. The pod uses as much disk space as the Kubernetes node has available. Ephemeral storage is available for the life of the SPSS Modeler runtime pod, which is allocated to each user when they work in SPSS Modeler or run a SPSS Modeler job. For more information about ephemeral storage, see Understanding ephemeral storage for your version of Red Hat OpenShift.

In general, SPSS Modeler needs to be able to write a temporary file that is at least three times larger than the original data set. For example, if the data file is 2 GB, SPSS Modeler requires 6 GB of disk space to process the data. However, if the available memory for SPSS Modeler is limited, more temporary disk space might be required. SPSS Modeler keeps temporary data in memory, but it saves temporary files to disk if the data size exceeds the available memory.
