Mikhail Khludnev commented on SOLR-3535:
----------------------------------------
Yonik,
do you mean XMLLoader (as well as other ones) should produce some form of
hierarchical document and some update processor will linearize such hierarchy
into the sequence and pass it into AddBlockCommand?
also how do you suggest to model doc hierarchy: as a SolrInputDoc subclass with
explicit relations collections or some magic collections values in the current
SolrInputDocument?
I'd like to emphasize the overall complexity - parent doc can have _several_
subdocs relations like SKUs/UPCs and Discounts, etc
PS pls check the parent issue SOLR-3076. there is a dilemma which feature set
to provide, your proposal is closer to "magic-knows-everything" schema
approach. I don't have strong disagreement about it, but just want to start
from pretty neat ability first. Anyway, looking forward to hear your
suggestions.

> 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?
