[GRASS-dev] Re: [bug #3877] (grass) r.to.vect, v.in.ascii use too much memory for millions of points

Andrew,

I first thought that your v.in.ascii fix enabled v.in.ascii to load
huge datasets *not* skipping the topology. After your clarification now
I see it was my mistake. Sorry if confusing.

Although I realize how important it is for many of us to be able to
load huge point datasets in any possible way, for now, like using this
no-topology hack, I hope there will one day be a real solution for
Grass to be able to process such big datasets in a normal, topological
way. Because propably the no-topology hack will be not suitable for
anything else besides points and propably we can't expect every single
vector module to be extended to support both non-topological and
topological vectors - also because there are GIS operations which
simply require a topological data model. The few 10^6 number of
features limit is a serious limitation in current Grass vector engine.
I wouldn't consider the bug solved, even regarding v.in.ascii alone.
But I do really appreciate all your effort towards making out as much
as possible of v.in.ascii for the moment. Thank you.

Maciek
