AWS marketplace Stardog disk usage virtual graph import

I want to validate the quality constraints in some data sources and it was suggested to me that importing the data in Stardog would have a better importance.
Also, I wanted to connect these data sources via reasoning rules and I wasn't able to achieve this between different virtual graphs.
Finally, as I have described here Stardog explorer does not visualize virtual graphs.

The size of the data that caused the error is around 15GB. We also want to import two more data sources. One with size 10GB and another 1GB.
