[gdal-dev] Reading an IntegerList from file

No, there's no existing parameter to avoid the truncation. What you could do is
just create a string with that format (or one you prefer)

You could use shapefiles by using a String field instead of IntegerList. SQLite
has no native support for list types either, so it will transform it into a
string too.

SQLite write performances can be improved dramatically by following the
recommandations in the "Performance hints" paragraph of
http://gdal.org/ogr/drv_sqlite.html . In particular, in my experience, on some
Linux kernels and EXT4 filesystem, defining the configuration option/env.
variable OGR_SQLITE_SYNCHRONOUS to OFF, leads to huge performance boosts.
