Erik Hatcher commented on SOLR-3535:
------------------------------------
bq. off hand, the big complication I see is how to deal with
UpdateProcesssorChains – should processors expect the nested SolrInputDoc or a
flattened version?
At first blush, I think we'd want a single SolrInputDocument passing through
the update processor chain AddUpdateCommand, and that document would be nested.
You'd need to keep that entire nested structure as a single unit for as long
as possible I think.
But of course there are cons.... update processors would need to coded to
handle nested documents explicitly, as currently something like a language
detection would only operate on the outer parent document automatically. Hmmm.

> I'd like to add the following update xml message:
> <add-block>
> <doc>....</doc>
> <doc>....</doc>
> </add-block>
> out of scope for now:
> * other update formats
> * update log support (NRT), should not be a big deal
> * overwrite feature support for block updates - it's more complicated, I'll
> tell you why
> Alt
> * wdyt about adding attribute to the current tag {pre}<add block="true">{pre}
> * or we can establish RunBlockUpdateProcessor which treat every <add>
> ....</add> as a block.
> *Test is included!!*
> How you'd suggest to improve the patch?
