---------------------------------------------------------------------
As far as I understand, this update processor is only for updates (if document
pre-exists). I see this as useful in cases where we're ingesting CSV files with
disjoint information about a document in different files. As an example:
||id||country||
|1| Japan |
|2| Russia |
||id||capital||
|1| Tokyo |
|2| Moscow |
Needs to be both ingested, and hence if both these are ingested through this
Update Processor, we would end up with 2 documents with 3 fields each (id,
country, capital).
Did I understand the motivation correctly?

> Add an Atomic Update Processor

> Key: SOLR-9530
> URL: https://issues.apache.org/jira/browse/SOLR-9530
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Varun Thacker
> Attachments: SOLR-9530.patch

>
> 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.
