Hi,

This feature is a bit hidden (right now; once we find it's really useful it
will be better documented). See
http://h2database.com/javadoc/org/h2/engine/DbSettings.html#COMPRESS

> Are there levels of compression that can be specified on the URL or
simply true/false?

Internally, yes, but you can't currently configure that. Currently, the
fast compression algorithm is used; in the future, the slow (better)
algorithm might be added as an option.

Regards,
Thomas
