Subject AW: SolrJ | Atomic Updates | How works exactly?
Date Sun, 13 Jan 2013 18:51:04 GMT
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?

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

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
RC1 for Solr4.1 early next week) or use a nightly build.
