Do you think PalDB support store data larger than physical memory?
I see in their introduction that PalDB relies on memory-mapped file which can be larger than physical memory. But on the other hand, PalDB emphasizes on their limitation "PalDB is optimal in replacing the usage of large in-memory data storage but still use memory (off-heap, yet much less) to do its job. Disabling memory mapping and relying on seeks is possible but is not what PalDB has been optimized for."

So if we use memory mapping mode of PalDB, does it support data larger than physical memory?
