Hi,
The shapefile system is in need of some work that I plan on doing at
some point in the future. The problem is that when the datastore was
written it did not use the mechanism for deleting records that is
built into the spec where you can null out a geometry indicated it was
deleted. So there is a funny mechanism that for each change the file
is written to a temporary file and then copied back (or moved) to the
original location. There is nothing to be done about this until this
issue is fixed. I plan on doing it but I have no time line as of
yet. At least not with some pretty nasty hacking and completely going
around the Datastore API to access the low level methods.

Hi All,
I am testing GeoTools for creating shape files. I typically have to
deal with a couple million points (~1 - 3 millions). Therefore, I am
looking for a way to sequentially write features to the shape-file.
I repeatedly generate a "FeatureCollection<SimpleFeatureType,
SimpleFeature> collection", add the collection to the
"FeatureStore<SimpleFeatureType, SimpleFeature> featureStore" and
call transaction.commit. It seems to me that whenever I call
transaction.commit all features in the featureStore are written to
file, as the more features I add the slower the transaction.commit.
How can I control the process of writing features to a shape file,
such that I can sequentially add a
"FeatureCollection<SimpleFeatureType, SimpleFeature> collection" to
the shape file?
Thanks,
Peter
