Ishan Chattopadhyaya updated SOLR-9530:
---------------------------------------
Attachment: SOLR-9530.patch
Updated the patch with formatting fixes:
Please always use braces around if/else/for blocks, even if they are one-liners.
I think a test should be added to validate the retry logic. The test should use
parallel threads to update different fields of the same document and assert
that both updates are made to the document finally.

> 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.
