Hi,

Spatialite is flexible and fast and quite easy to create at least up to 10
GB db file size. However, Java and native Spatialite binaries are tricky to
put to play together. The Spatialite community module is probably easy to
install
http://docs.geoserver.org/latest/en/user/community/spatialite/index.html but
it seems to use Spatialite version 2.4.0 while the current one is 4.1.0 and
I wouldn't recommend that.

However, Paul Ramsey is working on GeoPackage driver for GDAL and Boundless
is building a GeoPackage community module for Geoserver so perhaps the
answer is OGC GeoPackage, the shapefile of the hopefully near future.
