Is there an update on running ObjectDB purely in-memory?

Hi, I know that this has been asked, but the last time seems to be two years ago, so I'd like to know whether there is a change or an outlook regarding the topic: Is it possible, or planned, to run ObjectDB purely in-memory, without a any file on disk? Note that "file on RAM disk", which was proposed in the past, is not an option for the application I have in mind. It would need to be true in-memory mode, as supported by SQL databases like H2 or SQLite. Thanks, David ... but the last time seems to be two years ago, so I'd like to know whether there is a change or an outlook regarding the topic: ... to be true in-memory mode, as supported by SQL databases like H2 or SQLite.
