I've had a quick read through the features/FAQ and haven't been able to find a clear answer. I'm looking at replacing a setup of H2 where I have 40GB in-memory backed by 800GB on-disk, the 40GB in memory represents the first 40GB of the 800GB on-disk for super-fast recent entry searching, the records at the end continuously purge as the new ones come in(duplicate write, one to in-memory and one to on-disk). ... 11:02 I've had a quick read through the features/FAQ and haven't been able to find a clear ...
