You may of forgotten one step, if you are making use of a transaction you would
want to call transaction commit to write out the change.
Until that time the change is either:
- held in memory, and applied over top of the original content when reading
(for things like shape files); or
- only present in the JDBC transaction backing a JDBC datastore
If making sue of transaction AUTO_COMMIT (the default) performance can be
terrible! As an example the entire shapefile is written out on each change.
