Thanks erick,
the main reason why i want to use atomic updates is, to increase updating
existing kind of large documents.
So if under to cover, everything is the same (loading the whole doc,
updating, re-index the whole doc) it is not interesting for me anymore.
What is the best the most performant way to update a large document?
Any recommendations?
THANKS!

Betreff: Re: SolrJ | Atomic Updates | How works exactly?
Atomic updates work by storing (stored=true) all the fields (note, you
don't have to set stored=true for the destinations of copyField).
Anyway, when you use the atomic update syntax under the covers Solr reads
all the stored fields out, re-assembles the document and re-indexes it. So
your index may be significantly larger. Also note that in the 4.1 world,
stored fields are automatically compressed so this may not be so much of a
problem.
And, there's been at least 1 or 2 fixes to this since 4.0 as I remember,
so you might want to wait for 4.1 to experiment with (there's talk of
cutting
RC1 for Solr4.1 early next week) or use a nightly build.
