> 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.
