After importing this in h2, adding a few indexes, the size of my h2 mv.db database file is 3.6 gigs. Same csv files loaded up into an h2 "mem" database, all in ram, windows server shows usage of 85 gigs. The memory database just explodes in size compared to the file database, all else between the databases remains the same (tables + indexes etc).

Despite that H2 also stores the data on memory like the other databases, the architecture of database which is relational database management system decreases the performance of read operation.
