> I'd like to explore the idea of adding a new update processor to help ingest partial
updates.
> Example use-case - There are two datasets with a common id field. How can I merge both
of them at index time?
> Proposed Solution: 
> {code}
> <updateRequestProcessorChain name="atomic">
>   <processor class="solr.processor.AtomicUpdateProcessorFactory">
>     <str name="my_new_field">add</str>
>   </processor>
>   <processor class="solr.LogUpdateProcessorFactory" />
>   <processor class="solr.RunUpdateProcessorFactory" />
> </updateRequestProcessorChain>
> {code}
> So the first JSON dump could be ingested against {{http://localhost:8983/solr/gettingstarted/update/json}}
> And then the second JSON could be ingested against
> {{http://localhost:8983/solr/gettingstarted/update/json?processor=atomic}}
> The Atomic Update Processor could support all the atomic update operations currently
supported.
