Limit Cache Size on Disk

Dear Developers,

I am using CodeQL to analyze my database. In the command, I use `--max-disk-cache=200000` to specify the maximum disk space the cache would take in this query. However, when it finishes, the cache is taking to 1.3TB.

Would `--max-disk-cache` limit the disk to use? Or is there any other command to resolve this issue?

Thank you so much.

Start by checking the documented semantics of the `--max-disk-cache` option and compare them with the reported 1.3 TB result. Reproduce the command if possible, then determine whether the behavior is an implementation bug or whether the documentation needs to explain the cache limit and its units.
